If the problems don't appear on nvidia hardware it is a driver bug. Also opengl
is not the holy grail on improving ddraw performance in Wine. It depends a lot
on in what way the game is using ddraw in the first place. Even when it uses
ddraw in a 'opengl-friendly' way you in general need special opengl extensions
like GL_ARB_pixel_buffer_object to unlock the real acceleration. In general
opengl is worse or equal to gdi.
