Hello. 

Recently I tried  to play win32  version of UnrealTournament (first version) via wine. It worked before, but now failed. Updating wine to latest git (wine-1.7.51-201-g60d1d6f) not helped. I've bisected this down to mesa  commit in summary (bisect was  done on 10.6 branch, while bug was also present  on master, what I usually use).

Bug manifested itself as static desktop image instead of  fullscreen or even windowed game (in windowed mode it was not wine's desktop, yet not anything from game). I also suspect llvmpipe can be affected - because I tried with LIBGL_ALWAYS_SOFTWARE=1 and saw similar effect.

Hopefully below  you can find apitrace from successfull game startup:

Hw:
05:00.0 VGA compatible controller: NVIDIA Corporation G92 [GeForce 8800 GS] (rev a2) (prog-if 00 [VGA controller])

Note: I use older (patched) X server from 1.12 branch - but as far as I can see it doesn't expose anything new (sRGB fbconfigs, etc), and just changing nouveau_dri.so alone enough to make bug visible.
