[Intel-gfx] Graphical corruption on G965

[Alexander E. Patrakov]

Hello,

I now use Arch Linux on my desktop. Since Arch has upgraded Xorg to 
1.5.x, I started to see corruption on windows. This is not easy to 
trigger, so I can't bisect. This happens both with 1.4.x and 1.5.x Intel 
driver, but there was no such thing with xorg-1.4.x.

The corruption looks like incorrectly-painted (color stripes) 
rectangular parts of the window. XFCE Terminal is catching this most 
frequently (once per week), and I have no reliable way to reproduce 
this. The corruption moves together with the window and doesn't 
disappear when I minimize and restore the window, or when I open the 
popup menu just above the corrupted piece of window and then dismiss it.

I don't use compiz or any other compositing manager, and don't even have 
Option "Composite" in xorg.conf.

How to debug this?
