Can you add the glxinfo output of your geforce7? Perhaps it is related to
GL_ARB_map_buffer_range but I'm not sure if it is supported on your GPU. I'll
try to disable the extension here. It would also be useful to try some other
Wine versions to see if the issue existed there as well. If you find a version
which didn't have it, perform a regression test.
