--- Comment #2 from Bartosz Brachaczek b.brachaczek@gmail.com 2010-09-16 09:20:49 CDT --- Thomas: What gfx card do you use? Do you hardware accelerated 3D support in your driver? I think this is either a bug in Mesa's software renderer or a bug in Wine's OpenGL code that is only visible when using Mesa's software renderer (at least with r300c/r300g it works, and doesn't work with both classic swrast and Gallium3D llvmpipe).
