[Desktop-packages] [Bug 1098334]
Created attachment 92240 Text with errors Recently I'm noticing somewhat more 'weird' behavior - it might be related to my temporal usage of night releases of Mozilla (since rawhide version got somewhat broken) What is weird in this image is - the text was badly rendered AND it remained visible even when refreshed, even small scroll up/down left the text as is - it helped only to scroll text out of window and back. So I assume now the rendering happens to some off-screen memory - which is then transfered back to screen with errors - and refresh doesn't help with this case. (and it's a bit different then during typing text into input box). Another probably unrelated comment could be - even when 'glxgears' is running in parallel - the visual errors still happens during typing of this text. I'd have expect the glxgears manages to 'overfill' GPU queue (since it's rendering ~1300FPS with default window) also the flushes are probably completely different. And - there is no observable rendering error in gears window - only Firefox seems to be exposing them. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098334 Title: [gen4 sna] Font corruption Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: After enabling the SNA acceleration method and rebooting, I noticed that graphical glitches appeared in the letters on Chromium's tab bar during the mouse hover animation.

ok - while doing a very quick light check - at least on Firefox input window I do not observe any rendering bugs (which have been pretty simple to reach before).

Update after some new commits: 4c7b183fd21b461f9f18662c3b9d9732b6bef13d + Always patch - now gives me broken text lines in Thunderbird window. And it's now enough just to move the mouse over text and the text is changing and actually never renders correctly some letters.

(In reply to comment #160) Typical, it appeared stable through my firefox testing, but if you try reverting b7565a26401e283df94b68019e8093f8104428f4, I expect the corruptions to disappear again. Yep - correct revert of this commit make MAX_VERTEX 1 again producing correct rendering - even thought it's again noticable slower - thus now it's clear why I've considered it usable with MAX 1 before (in my comment 155).

I think nice illustration could be - that while before with MAX 9 it seemed like i.e. gnome-terminal running top was not really rendering broken characters - it now seems to show a lot of messed characters.

(In reply to comment #92) Removed an older hack and had to reduce the max further. Bah, humbugs. OK, this time I'm definitely not able to reproduce the issue so far. Maybe it will some extra time - hard to say now - but before it has took me just minutes to get the issue visible. intel_gpu_top now shows only few lines busy to 1% during scroll. The bad part is - while before I've been getting 3.7Mchar/s in x11perf -aa10text - now it's like 1.3Mchar/s so significantly slower. So the question here would be - isn't the corruption based on triangle surface size ? So i.e. GPU is able to process a lot of small ones - but has bug with bigger ones ?

(In reply to comment #96) (In reply to comment #93) The bad part is - while before I've been getting 3.7Mchar/s in x11perf -aa10text - now it's like 1.3Mchar/s so significantly slower. That's the sacrifice, we have to stop sending commands to the GPU and wait for it complete those in flight (quite frequently). Or else new rectangles overwrite vertex entries still being used by later entries So the question here would be - isn't the corruption based on triangle surface size ? So i.e. GPU is able to process a lot of small ones - but has bug with bigger ones ? But as I said before - if that would be plain hw defect - IMHO it would simply always appear - but it seems like it's working for a while - then 'something' happens - and flickering starts to appear - with (assumingly) same amount of texels/triangle/vertices - and than something again may happen, and the problem is gone for a while. Not really, you have to predict when a VUE being used by the end of the pipeline will be overwritten by a new rectangle at the start of the pipeline. This is completely internal state - the primitive command we want to feed to the GPU can contains thousands of rectangles. Instead of counting Well I've tried even 8 max triangles - and the error appeared after a while, so far '6' is magic. rectangles, you want to start counting fragments (actually texel reads since that will be the ratelimiting factor) and flush if we queue up too much work for the GPU. If you also model how fast the gpu is retiring fragments so But in case the same page is rendered with problems as well as without problems, then it doesn't look like texel read is problem, it rather looks like some kind of memory mapping/ordering. Also is there some explanation why intel_gpu_top is showing so much higher GPU usage when the flickering is visible ? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098489 Title: [gen4] Corruption in Chrome omni bar results using Intel SNA Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: After enabling Intel SNA the favicons in the omnibar search results are corrupted.

Also is there explanation with the max value 64 starts to make problems with text rendering in gnome terminal ? i.e. I'd have expected if there would be a large press on GPU - but in this case it just appear random pixel start to be drawn instead of some letter - maybe some font cache corruption ? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098489 Title: [gen4] Corruption in Chrome omni bar results using Intel SNA Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: After enabling Intel SNA the favicons in the omnibar search results are corrupted.

[Desktop-packages] [Bug 1098489]
(In reply to comment #107) The quick answer is that if ever see it with MAX_FLUSH_VERTICES set to 1, then it is a different issue. Please do be aware that all current kernels since 3.7 do have a coherency issue, the fix will not arrive before 3.10.1 (outside of drm-intel trees). Could you please commit here the link to the needed kernel commit so I could check if it's fixing issue for me? Also it's then easier to see which upstream vanilla kernel will have it. And also it will be good to remove the low triangle limitation. Yes memory coherency seems like very good explanation for problems I'm seeing. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098489 Title: [gen4] Corruption in Chrome omni bar results using Intel SNA Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: After enabling Intel SNA the favicons in the omnibar search results are corrupted.

Unsure if it's related to anything and test seems to be lenghty -
but there seems to be some observable pattern.
Anyway - could I help here with testing some patch - or do you get same
errors yourself on your available hardware ?

[Desktop-packages] [Bug 1098489]
Hmm - after doing some more experiments - the high load on GPU seems to be pretty much the thing which make the problem visible. Another interesting thing is - it's usually enough to just 'reload' the very same page in Firefox and the load goes down to ~1% and everything is ok. Also the kernel perf top doesn't seem to be showing anything interesting. And a side note - when intel_gpu_top is running - the laptop is actually giving some whistling noise not really pleasant for longterm usage ;) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098489 Title: [gen4] Corruption in Chrome omni bar results using Intel SNA Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: After enabling Intel SNA the favicons in the omnibar search results are corrupted.

[Desktop-packages] [Bug 1098489]
(In reply to comment #84) Yes, that is characteristic of this bug. The internal vertex/texture coordinates that are being passed along the GPU pipeline become corrupt (it looks like we overflow a small ring buffer). The only effective approach If it would be plain 'overflow' - than I'd be seeing this kind of corruption always right after X starts. But it seems like i.e. Firefox must be used for certain period of time, to make these corruptions visible. Surely I'm not not an expert on GPU programming - but maybe when the physical memory gets fragmented enough after some usage there are some 'cached bo' objects - maybe their usage is not fully synchronized? Also the effect could also disappear (I've not yet noticed any particular way for that) - so then Firefox scroll even the very same pages and there is no problem (i.e. now I run still the same session - and I do not get any visible problem) I've found so far has been to keep the number of rectangles inside the GPU pipeline below a magic value - but that is quite tricky here, and the Well why the number would sometimes work for ours without a single visible problem, and suddenly start to show them again? My impression here is, when this problem is visible, it looks like operations is working with 'wrong' parameters (i.e. sometimes I see the image stretched, inverted, zoomed) Maybe parameters have only some bits mangled - not fully synchronized memory from CPU for GPU?? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098489 Title: [gen4] Corruption in Chrome omni bar results using Intel SNA Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: After enabling Intel SNA the favicons in the omnibar search results are corrupted.

I think nice illustration could be - that while before with MAX 9 it seemed like i.e. gnome-terminal running top was not really rendering broken characters - it now seems to show a lot of messed characters. On the other hand - MAX 1 seems to be now more fluent then before - so except for some dramatic drops in performance in benchmark tools like 'x11perf -aa10text' it seems to be quite usable. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098489 Title: [gen4] Corruption in Chrome omni bar results using Intel SNA Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: After enabling Intel SNA the favicons in the omnibar search results are corrupted.

Maybe this bug could be more easily tracked down when the amount of vertices is actually much higher - since in this case it seems to crash almost immediatelly. I understand there is some 'maximum queue' size GPU could handle - but the engine should be able to track size of all commands and not outgrown it. So what else could break ordering ? As it's very easy to trigger the problem with higher max - maybe it could be used to deduce which part of code unexpectedly touches the command queue ? (but of course it's just my naive assumption about how the SNA driver works). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098489 Title: [gen4] Corruption in Chrome omni bar results using Intel SNA Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: After enabling Intel SNA the favicons in the omnibar search results are corrupted.

(In reply to comment #99) (In reply to comment #97) (In reply to comment #96) (In reply to comment #93) The bad part is - while before I've been getting 3.7Mchar/s in x11perf -aa10text - now it's like 1.3Mchar/s so significantly slower. But as I said before - if that would be plain hw defect - IMHO it would simply always appear - but it seems like it's working for a while - then 'something' happens - and flickering starts to appear - with (assumingly) same amount of texels/triangle/vertices - and than something again may happen, and the problem is gone for a while. It does. You do not have quite as much control over your tests as you presume. Well I understand there are some weird things underneath - but when I've a page where the scrolling up/down is showing heavy intel_gpu_top usage, and flickering of pictures is visible - then I make nothing else then page reload - I've just naive assumption, that this redrawn page is just using different memory buffers - but otherwise the number of graphical objects pushed to GPU should be approximately the same. (I'm using plain good old xfce, so no fancy Gnome3 shell composite desktops...) No. I did not say the texel reads where the problem, just an indicator as to how long the EU would execute any particular shader for a fragment. Also there is only a single sampler and many EU running many more threads, so contention will also play a factor into how long each fragment takes to process, and so how long buffers will be active for. Look more closely at what it is going on, it is clearly that the hardware is not tracking lifetimes of its URB correctly. Also is there some explanation why intel_gpu_top is showing so much higher GPU usage when the flickering is visible ? Other than the flickering correlates with GPU activity? Well the same page could be scrolled with either i.e. 15% 'render busy' - and no flickering - or with ~50% 'render busy' and visible problems. I could make a debug build - but it would be probably needed to have some kind of 'signal support' to dump needed data when necessary instead of logging GB of data all the time. i.e. I'd have expected if there would be a large press on GPU - but in this case it just appear random pixel start to be drawn instead of some letter - maybe some font cache corruption ? It's still the same bug. So maybe we could start at this - since MAX 64 is giving the problem exposed very easily - it's enough to run gnome-terminal on my desktop. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098489 Title: [gen4] Corruption in Chrome omni bar results using Intel SNA Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: After enabling Intel SNA the favicons in the omnibar search results are corrupted.

Well I'm curious how this explains this - I've taken current git - changed the value to '44' - and I'm typing this text. I could see a lot of errors during text typing - but these errors seems to be somehow limited only to certain regions of shown text. It's not destroyed everywhere - only in some particularly piece and in particular time - it's kind of weird defect to observe - and it also happen for only some specific use-case i.e. my text edit 'fte' which is using X drawing code has absolutely no issue - all characters are always correct. But in firefox - typing this BZ I could see a lot of changing letters (usually everything after 10 letter on the line is weirdly changing - like if the font cache would be not working correctly. Typing on keyboard shows rending bugs - as soon as right mouse button is hit - everything is instantly redrawn correctly and pop window is shown. Another thing I notice is - I've about 20 lines of email headers in thunderbird. And exactly only the 4th line is showing problems with letters - even when I just move the mouse over the TB window - this text is being continuously modified - but everything else in that window is without any problem. So if you say - there is hw bug - how is that - it could very easily render everything correctly ? Why only certain portions of text have distortions - why it's not randomly spread over the whole screen (which I'd have expected for time collisions)? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098489 Title: [gen4] Corruption in Chrome omni bar results using Intel SNA Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: After enabling Intel SNA the favicons in the omnibar search results are corrupted.

It could be probably worth to mention - that when I'm flipping between Firefox tabs I could have scrolling tabs without any issue (and low GPU usage), while flipping to other tabs and scrolling in them increases GPU to high levels and visual problems are present. So in the moment the problem appears - it's rather local to certain tabs. And as I said - it's often enough to reload tab to temporarily fix the problem. And as of typing current BZ message - I've noticed (using MAX 6) that letter 'a' in the word 'certain' above has been for a while drawn only from one half - and after I've typed whole sentence it's been just refreshed properly.

Maybe this bug could be more easily tracked down when the amount of vertices is actually much higher - since in this case it seems to crash almost immediatelly. I understand there is some 'maximum queue' size GPU could handle - but the engine should be able to track size of all commands and not outgrown it. So what else could break ordering ? As it's very easy to trigger the problem with higher max - maybe it could be used to deduce which part of code unexpectedly touches the command queue ? (but of course it's just my naive assumption about how the SNA driver works). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098334 Title: [gen4 sna] Font corruption Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Triaged Bug description: After enabling the SNA acceleration method and rebooting, I noticed that graphical glitches appeared in the letters on Chromium's tab bar during the mouse hover animation.

Well I'm curious how this explains this - I've taken current git - changed the value to '44' - and I'm typing this text. I could see a lot of errors during text typing - but these errors seems to be somehow limited only to certain regions of shown text. It's not destroyed everywhere - only in some particularly piece and in particular time - it's kind of weird defect to observe - and it also happen for only some specific use-case i.e. my text edit 'fte' which is using X drawing code has absolutely no issue - all characters are always correct. But in firefox - typing this BZ I could see a lot of changing letters (usually everything after 10 letter on the line is weirdly changing - like if the font cache would be not working correctly. Typing on keyboard shows rending bugs - as soon as right mouse button is hit - everything is instantly redrawn correctly and pop window is shown. Another thing I notice is - I've about 20 lines of email headers in thunderbird. And exactly only the 4th line is showing problems with letters - even when I just move the mouse over the TB window - this text is being continuously modified - but everything else in that window is without any problem. So if you say - there is hw bug - how is that - it could very easily render everything correctly ? Why only certain portions of text have distortions - why it's not randomly spread over the whole screen (which I'd have expected for time collisions)? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098334 Title: [gen4 sna] Font corruption Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Triaged Bug description: After enabling the SNA acceleration method and rebooting, I noticed that graphical glitches appeared in the letters on Chromium's tab bar during the mouse hover animation.

(In reply to comment #136) The issue that the VUE (which is a memory slot used by the GPU for a vertex entry) are reused by a second thread before the first thread is complete, causing the first thread to generate invalid texture coordinates and corrupt rendering. That is a hardware read-write hazard bug (or at least I have not found any controls in the EU state to prevent it). I don't think it's that easy to explain - The typical problem in my case is - when I freshly start the Xsession - I do not observe any rendering bug. I need to use this machine for a while, to start to get those errors. So if there would be some 'easy to trigger hardware race' - it should be reproducible all the time. But in my case it seem - the probability increases over the time heavily - maybe with the amount of cached BO segments ? Or maybe it depends on how the memory order is set - i.e. the problem is triggered when certain memory read pattern start to appear ? Since once the issue of flicker starts - it then happens all the time - and then suddenly it disappears for a while again ? So maybe there needs to be prohibited some memory offset/alignment of buffers with vertices ? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098334 Title: [gen4 sna] Font corruption Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Triaged Bug description: After enabling the SNA acceleration method and rebooting, I noticed that graphical glitches appeared in the letters on Chromium's tab bar during the mouse hover animation.

Just to add some more comment on MAX_FLUSH_VERTICES - when set to valu 96 - it gives the highest throughput on x11perf -aa10text 3.7MChar/s - using any higher value doesn't make any different (so the max seems to be somewhere between 64-96] Also when this 3.7MChar is rendered - the parallel move of some other window on the screen becomes very slow - so engine gets overloaded ??

(In reply to comment #84) Yes, that is characteristic of this bug. The internal vertex/texture coordinates that are being passed along the GPU pipeline become corrupt (it looks like we overflow a small ring buffer). The only effective approach If it would be plain 'overflow' - than I'd be seeing this kind of corruption always right after X starts. But it seems like i.e. Firefox must be used for certain period of time, to make these corruptions visible. Surely I'm not not an expert on GPU programming - but maybe when the physical memory gets fragmented enough after some usage there are some 'cached bo' objects - maybe their usage is not fully synchronized? Also the effect could also disappear (I've not yet noticed any particular way for that) - so then Firefox scroll even the very same pages and there is no problem (i.e. now I run still the same session - and I do not get any visible problem) I've found so far has been to keep the number of rectangles inside the GPU pipeline below a magic value - but that is quite tricky here, and the Well why the number would sometimes work for ours without a single visible problem, and suddenly start to show them again? My impression here is, when this problem is visible, it looks like operations is working with 'wrong' parameters (i.e. sometimes I see the image stretched, inverted, zoomed) Maybe parameters have only some bits mangled - not fully synchronized memory from CPU for GPU?? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098334 Title: [gen4 sna] Font corruption in Chromium tab bar Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Triaged Bug description: After enabling the SNA acceleration method and rebooting, I noticed that graphical glitches appeared in the letters on Chromium's tab bar during the mouse hover animation.

It could be probably worth to mention - that when I'm flipping between Firefox tabs I could have scrolling tabs without any issue (and low GPU usage), while flipping to other tabs and scrolling in them increases GPU to high levels and visual problems are present. So in the moment the problem appears - it's rather local to certain tabs. And as I said - it's often enough to reload tab to temporarily fix the problem. And as of typing current BZ message - I've noticed (using MAX 6) that letter 'a' in the word 'certain' above has been for a while drawn only from one half - and after I've typed whole sentence it's been just refreshed properly.

(In reply to comment #96) (In reply to comment #93) The bad part is - while before I've been getting 3.7Mchar/s in x11perf -aa10text - now it's like 1.3Mchar/s so significantly slower. That's the sacrifice, we have to stop sending commands to the GPU and wait for it complete those in flight (quite frequently).

Not really, you have to predict when a VUE being used by the end of the pipeline will be overwritten by a new rectangle at the start of the pipeline. This is completely internal state - the primitive command we want to feed to the GPU can contains thousands of rectangles.

If you also model how fast the gpu is retiring fragments so But in case the same page is rendered with problems as well as without problems, then it doesn't look like texel read is problem, it rather looks like some kind of memory mapping/ordering.

Hmm - after doing some more experiments - the high load on GPU seems to be pretty much the thing which make the problem visible. Another interesting thing is - it's usually enough to just 'reload' the very same page in Firefox and the load goes down to ~1% and everything is ok. Also the kernel perf top doesn't seem to be showing anything interesting.

It does. You do not have quite as much control over your tests as you presume. Well I understand there are some weird things underneath - but when I've a page where the scrolling up/down is showing heavy intel_gpu_top usage, and flickering of pictures is visible - then I make nothing else then page reload - I've just naive assumption, that this redrawn page is just using different memory buffers - but otherwise the number of graphical objects pushed to GPU should be approximately the same. (I'm using plain good old xfce, so no fancy Gnome3 shell composite desktops...) No. I did not say the texel reads where the problem, just an indicator as to how long the EU would execute any particular shader for a fragment. Also there is only a single sampler and many EU running many more threads, so contention will also play a factor into how long each fragment takes to process, and so how long buffers will be active for. Look more closely at what it is going on, it is clearly that the hardware is not tracking lifetimes of its URB correctly. Also is there some explanation why intel_gpu_top is showing so much higher GPU usage when the flickering is visible ? Other than the flickering correlates with GPU activity? Well the same page could be scrolled with either i.e. 15% 'render busy' - and no flickering - or with ~50% 'render busy' and visible problems. I could make a debug build - but it would be probably needed to have some kind of 'signal support' to dump needed data when necessary instead of logging GB of data all the time. i.e. I'd have expected if there would be a large press on GPU - but in this case it just appear random pixel start to be drawn instead of some letter - maybe some font cache corruption ? It's still the same bug. So maybe we could start at this - since MAX 64 is giving the problem exposed very easily - it's enough to run gnome-terminal on my desktop. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098334 Title: [gen4 sna] Font corruption in Chromium tab bar Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Triaged Bug description: After enabling the SNA acceleration method and rebooting, I noticed that graphical glitches appeared in the letters on Chromium's tab bar during the mouse hover animation.

(In reply to comment #107) The quick answer is that if ever see it with MAX_FLUSH_VERTICES set to 1, then it is a different issue. Please do be aware that all current kernels since 3.7 do have a coherency issue, the fix will not arrive before 3.10.1 (outside of drm-intel trees).

(In reply to comment #78) No hope to solve this and many, many other bugs on gen4 - here and in mesa. I suggest to buy new laptop because it doesn't have any sense. Some time ago I also thought that it has. Now I have Intel Ivybridge and Nvidia through Bumblebee and both runs almost perfect :-) Regards Sure I could buy and run Windows, and forget about buggy Linux drivers ;) But we are not all the same - I still hope it can be fixed :) Enjoy your non free proprietary Nvidia drivers -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098334 Title: [gen4 sna] Font corruption in Chromium tab bar Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Triaged Bug description: After enabling the SNA acceleration method and rebooting, I noticed that graphical glitches appeared in the letters on Chromium's tab bar during the mouse hover animation.

(In reply to comment #74) I think I've a sort of positive message here at least on my T61 - now using upstream git commit 8f340f90f4b2f269d6308d0bd31fbc2a5f579608 I'm no longer observing corruptions while scrolling Firefox pages. So some recent commit is probably behind this change. Before I've used 14 days older commit and I've been able to easily see those corruptions. Now it looks like they are gone. Of course I'll make a longer observation here - but so far it looks promising. Ok - it seems that on the longterm run the corruptions starts to appear again. So it seems to be related how the memory is being used over the time. But with my 4 days uptime - now I see easily images corrupted during the scroll in firefox. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098334 Title: [gen4 sna] Font corruption in Chromium tab bar Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Triaged Bug description: After enabling the SNA acceleration method and rebooting, I noticed that graphical glitches appeared in the letters on Chromium's tab bar during the mouse hover animation.
