I too have the same problem. I have attached a screen-shot of what is happening. Basically, the whatever program is on top, gets pushed behind the preview. When moving the preview window, it leaves a trail of images of the preview. The screen just fails to refresh, even hitting F5 at the desktop to refresh the desktop does not work. The only thing to clear the extra images is to drag another program over that portion of the screen. It makes it really hard to choose my power management options when I can't even see them! I am running Ubuntu 8.10 Intrepid. I had the same problem in 8.04 by the way. My card is a Intel Graphics Media Accelerator 950.
