Hi, I'm using a 945GM with the xf86-video-intel driver (version 2.13.0).
The used kernel is 2.6.36 with KMS enabled.
In console mode everything is OK. X with the VESA driver produces normal graphics, too. But X with the intel driver is drawing graphics as seen on the screenshot (why is it possible to take screenshots from graphic glitches?).
Disabling DRI (Option "DRI" "false" in xorg.conf) doesn't change anything.
Option "Shadow" "true"
the graphic works with the intel driver, but I think it's not the best workaround.

For testing I updated to the newest git source of libdrm and xf86-video-intel-2.13.901 couse of hardware accelerated 3D.
Now (with Option "Shadow" "true") the "strange pixels" are only in 3D apps (see new Screenshot)
(Accelerated) videos or composited effects (like the panel) are working as they should (but only with Option "Shadow" "true" - without this option even videos have the problem (with 2.13.901 and 2.13.0)).
Maybe this helps identifing the problem.
I made a little video showing the problem better than the screenshot with 2.13.0: http://home.mnet-online.de/tinka/out.avi

Is this really the same bug?
He has another card, a git version of mesa, another platform and he has this only in one game.

I asked the autor of the other bug if his problem is still there when he downgrades to mesa-7.8.2 (which is the version I'm using) and he sayd _NO_!
So why are you so sure that we have the same bugs?
The other bug is fixed but the fix doesn't help here.
I updated to xf86-video-intel-2.14.0.
In 2D graphics it's ok to use "Shadow" "true" but 3D graphics (glxgears for example) have the glitches now (with or without "Shadow" "true")
Now I tried to run xf86-video-intel-2.14.0 with a 2.6.37-rc8 kernel (my normal kernel is a 2.6.36 one) and the problem still exists.
BUT: When drawing 3d Applications (like glxgears) the windo-decorations are going crazy (I start the window: no decorations, I klick on it: half of the decorations, I klick on another window: no decorations, for example) and sometimes X is just crashing like this (crashed after klicking into the window of glxgears):

Does this still happens with latest versions of the components?
