Reinstall a video driver suitable for your video card and directx. If the problem persists, change video renderer to vmr7 windowed or something else.

I update both my video and audio card drivers. I install DirectX 9.0c too, but without success.
When I choose vmr7 windowed I have the same problems in the second image.
