If you mean the problems with DX and alt - tabbing: There are threads on that in the bugsection.
That and the mouse lag are the only probs I know of. OpenGL has none of both (textures can't disappear as OpenGL has no texture managing as DX, nor can OpenGL render 8 frames ahead which leads to the mouse lag problem)
