Created attachment 24290 [details] xorg log In some cases when using intel driver the screen is corrupted. This happens on: xserver 1.6 intel driver from master libdrm from master drm from drm-intel-next but only if KMS is disabled.
Created attachment 24291 [details] when viewing http://filmfactor.pl/ in firefox
Created attachment 24292 [details] on kde4 logout screen
Note that this corruption is easy to repeat but it's specific. For example it is visible only on some web pages and in kde so far only on logout screen. The rest looks fine.
