Hardware: Radeon 6850

Software: 64bit Gentoo, game running via Wine (32bit), git versions of libdrm, xf86-video-ati, kernel version 3.7(ish) and latest 3.8 rc + drm-next branch

The issue is affecting light effects, spell effects, etc. (see screenshots).

Bisecting leads to this commit:

There is already one bug report mentioning this commit [1], not sure if it's the same issue.

Besides PoE, I also encontered similar problem in StarCraft2, I didn't checked if it's the same problem, text/fonts on the loading screen shows the same "corruption", however the game also hangs the GPU, so bisecting it might be a bit problematic.

Please retest with 496928a4, as this commit reverts
this change for desktop GL. (The behavior is retained
for GLES3.)
Comment 6 Wojciech Pyczak 2013-02-14 10:27:33 UTC 
I'm currently using latest version (cb4616d3) and the issue is gone.
