[Wine] AMD/ATI + Linux + WINE = FAIL... all around.

[Austin English]

It's not the answer you want, but Wine needs _a lot_ of features from
the graphics drivers that ATI simply does not provide. In addition,
some recent D3D work regressed on ATI drivers, complicating things a
bit more. Nvidia has been better about providing good drivers, unlike
ATI. Most native games don't require as many resources and hence, work
fine. You might try disabling compiz if you haven't already, as it
conflicts with wine. Also, try filing a bug with ATI. They won't fix
bugs exposed by wine's graphics tests, but will fix bugs affecting
games...
