--- Comment #6 from Tuomo Kohvakka tuomo.kohvakka@iki.fi 2008-02-18 08:03:40 --- Do you have any idea what goes wrong with GLSL? Is more likely driver bug or wine bug? I'm using binary NVIDIA driver 169.09 (geforce 6800) with xorg 1.4.0.90.
I guess it would be nice if someone else could confirm this too?
