I also don't expirience such issues, though, in order to run it on my PC, I disabled almost all graphic effects whatsoever... maybe it's an error in some of the highres shaders.

Other than that, I had similar errors some time before and solved it by completely uninstalling the graphic drivers and DirectX and reinstalling them (and no, just over-installing them didn't help).

Maybe that helps?
