I was able to reproduce that stack trace from Xorg log and intel driver is not an issue here at all.
I found out that the cause of this is the fast spinning mouse wheel. I have a mouse with a wheel which can be scrolled like in 'free roam' mode, without that 'clicks', you know. And if I scroll too fast that stack appears. As before dmesg is clean from any i915 errors and no error state was caught. So, that stack is not related to the bug at all. -- 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/1144558 Title: Images corruption in firefox when using "sna" Status in X.org xf86-video-intel: Confirmed Status in “xserver-xorg-video-intel” package in Ubuntu: Fix Released Status in “xserver-xorg-video-intel” source package in Raring: Fix Released Bug description: Since "sna" is in using in raring users are reporting pixmap corruptions in firefox, I see the issue on an i5 cpu.
