[Bug 782855] Re: missing pixels (horizontal lines) in font rendering
Not fixed here. I upgraded the Vaio to Oneiric yesterday and am seeing font corruption after running it for about 2.5 hours this morning with several suspends. I'm also seeing the i915 module loaded in oneiric. I can't test what module it used in natty (replaced that partition in the upgrade) but Debian Squeeze, which also shows the problem, loads i915 just like oneiric does. I'm not convinced using lots of fonts makes a difference -- I've seen it when I wasn't doing much more than rehearsing/presenting a talk, with only a few fonts on the slides. I think running for a while is more important (usually several hours, though once or twice I've seen it sooner than that).

[Bug 782855] Re: missing pixels (horizontal lines) in font rendering
Ha! Sure enough, the quickest way to get a bug to manifest is to deny its existence. It is NOT fixed globally in Oneiric. I made 2 useage changes in the past few weeks that contributed to my not noticing any flaws: 1) switched primary browser from Firefox to Chrome, and 2) switched terminator shell's font from Monospace 8pt to Ubuntu Mono 8pt. I just changed the terminator font back a day or two ago and yep, it's wrecked again. Observations: - bug manifests in terminator shell with Monospace 8pt font, but not with Ubuntu Mono at any size. After changing font sizes and faces for a while, the bug is completely gone from the font chooser, and does not appear in the shell after closing prefs --- but, after switching to another app for a while the font is once again damaged in a novel way. This happens with Monospace only, as far as I can see. - bug does not manifest in Chrome 14.0.835.186 at all. (see zooming note below) - bug manifests in Firefox 7.0.1 -- nb. compared same page [ http://getfirebug.com/firstrun#Firebug%201.8.4] in both firefox and chrome. - bug manifests in Thunderbird 7.0.1 in html emails, but NOT in message lists, menus, etc. - browser view zooming causes what? font re-rendering? In Firefox, zooming in and out repeatedly with ctl+, ctl- caused the bug to appear *almost* at random. Sometimes the fonts were damaged in the same way, but after a few passes the damage changed location, moving from letter to letter and line to line. No *pattern* of change was observed, per se. The same actions in Chrome did not provoke any damaged fonts to appear, even using the same page as with Firefox. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/782855 Title: missing pixels (horizontal lines) in font rendering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/782855/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 782855] Re: missing pixels (horizontal lines) in font rendering
I see the problem almost (but not quite) exclusively in browsers (both firefox and webkit-based, though I don't run chrome on that machine); never in simple apps like xterm or emacs, or in gimp. Once it starts manifesting, its form will persist (e.g. if two lines of pixels are missing from lowercase b, then that will always be the case) through zooming, moving the browser window, reloading, opening new tabs, etc. However, if I quit firefox and restart it, I'll see a different pattern (e.g. it might be G and x mis-drawn now, rather than b) and that will persist through that run of firefox (but new letters might eventually start being affected as well). Once it starts, there's no chance of quitting and restarting to get a browser that has NO damaged letters; but sometimes I can get one where the bad letters are less common ones so I can still read pages for a while and can postpone rebooting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/782855 Title: missing pixels (horizontal lines) in font rendering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/782855/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

In the meanwhile I've changed my laptop so I'm afraid I won't be of much help on this. I imagine this kind of bugs are pretty complex to spot but unfortunately push people moving to different OS's, at least for laptops (I've moved to OS X myself, even if I'm still fully-Ubuntu on the desktop).

[Bug 782855] Re: missing pixels (horizontal lines) in font rendering
Hey akkzilla, You filed this bug report against natty, but I see it's still open and doesn't appear to have much activity recently. So, now that oneiric is released and stable, this may be a good point for you to upgrade and re-test if this issue is still present there. If it's solved in the new release and you think it's worth backporting the fix, please indicate that. Or if having the fix in the new release is good enough, feel free to close out the bug (or let us know and we'll close it.) If it's not solved, leave the bug report open. I can't promise we'll get to it (we get way more bugs filed than we can usually get to), but your testing and feedback can help out if and when we do. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Confirmed = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/782855 Title: missing pixels (horizontal lines) in font rendering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/782855/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 782855] Re: missing pixels (horizontal lines) in font rendering
This is bizarre. I have the same problem with the nouveau driver. I got around it by installing the experimental open source 3D driver. It seems odd that two drivers have the same problem. I am also using 11.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/782855 Title: missing pixels (horizontal lines) in font rendering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/782855/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Ignore that comment about heat. After more experimentation, I do occasionally see the problem right after booting, and it almost always persists through a suspend cycle. Exiting/restarting X doesn't cure it, but rebooting (even with no appreciable time for cooldown) does. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/782855 Title: missing pixels (horizontal lines) in font rendering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/782855/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 782855] Re: missing pixels (horizontal lines) in font rendering
I have a theory that this may be related to heat. I almost never see bad fonts immediately after booting, but after a long session where the fan has been on a lot, the fonts will get worse and worse. If I suspend for a while, sometimes they get better, but I have seen corrupted fonts immediately upon resuming from suspend, so I'm not entirely convinced. I should stress that this doesn't happen in Lucid, so even if it's heat releated, it's definitely caused by a software change. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/782855 Title: missing pixels (horizontal lines) in font rendering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/782855/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
