Well I should wait a while before posting a comment about magic value 6. I'm now observing flickering with value 6 as well.
So yeah - it's more or less time related - and it takes more or less time until the problem becomes visible. 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/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.
