Bug #: 31190
           Summary: Regression: Starcraft II jitters / stutters with wine

Hello,
I have stumbled upon what I believe is a regression introduced somewhere
between 1.5.6 and 1.5.7. Starcraft II's behaviour is considerably worse since
1.5.7 - while FPS remains the same, the game is much less responsive, and even
moving the screen around one can feel quite a lot of jerkiness.

This problem persists with 1.5.8.

System info:
Arch Linux 64bit,
Linux 3.4.4
Mesa 8.0.3
Xorg 1.12.3
xf86-video-ati 1:6.14.6

works fine with wine 1.5.6 (and before)
works badly with wine 1.5.7 and 1.5.8

If you need me to test anything, shout.

Cheers,
Peter
