There is no general bug.
Most bugs like that arise from 3 paths:
1. Unofficial (modded) graphic drivers for NVidia and AMD graphic cards. While they are a good idea, most of them removed the DX7 support from the drivers -> straight crash (on Omega Drivers for example) if you don't use OpenGL
2. Stone Age hardware which is just not able to do 2D through 3D on a level that does not go wacky or worse: hardware that makes DX think it is able to and is not (some older intel onboard as well as some SiS onboard)
3. OpenGL
Onboard in general disliked it heavily until 2 years ago (especially a problem as most of them are still used as intel onboard were and are the most sold graphic chip today with over 50% marketshare) and SiS still seems to have problem with it.
