It's fixed! (for me) - mesa git did the miracle :)

FYI - changing CPU's to performance didn't had any influence. I've made another
screenshot, this time with xwd (thanks for the tip btw) and with GTT-usage
(thangs for pointing that out - that was a copy paste error). Don't know if
it's still important but i'll upload it anyway.

Settings for vally are as followed:
Quality: Ultra
Stereo 3d: Disabled
Monitors: Single
Anti-aliasing: Off
Full Screen: Yes
Resolution: 2560x1600
