Hi xaotik, that's definitely going to be some problem in your video drivers.

I'd recommend updating to the latest version, that will probably solve it. If it doesn't you may need to instead go to a slightly older one instead.

Those apps both use OpenGL instead of Direct3D, so they actually use a completely different driver infrastructure than what MoI ends up using.

So whatever driver problem you currently have seems to be in the Direct3D area. Most of the time it is the other way around (with the OpenGL drivers being more flaky especially with ATI), but not for your case here it seems.

Nothing really... It just really sounds like there is a bug in the video drivers that gets exercised by the particular combination of drawing commands that MoI happens to send to the card.

Your best bet is to update to the latest drivers, there is a good chance that will solve it for you.
