Update and new information:

The bug returns with wine when forcing the use of the ffp_fragment_pipeline,
this is the fixed-function variant.

My current tests were all done with the mesa-7.1 release, which still has this
bug. However when forcing the use of the Mesa software rasterizer
(LIBGL_ALWAYS_SOFTWARE=1) the texture corruptions disappear.

For me this is a strong indication that there is no bug in the
ffp_fragment_pipeline implementation of wine, but in the i915 DRI driver.

I then upgraded to the recent pre-release mesa-7.2_rc1 and the appearance of
the bug changed. The texture corruption with mesa-7.1 and older versions was
always colorful.

Now with mesa-7.2_rc1 the corrupted texture parts are completly white. Some
commit between 7.1 and 7.2_rc1 must have changed how the bug operates.

I'm still trying to figure out how to bisect this commit. I would appreciate
some help, since I'm trying to avoid using "make install". Maybe some
preloading method is best?

Greets,
Tobias
