there's a couple of solutions/workaround
herePS: google is your friend. Took me literally 15 seconds to find a match. And that was because my keyboard randomly dies on me when typing.
edit: this is also another possible solution, apparently:
some guy wrote: The blog post from the developers that were working on it said that it involves a corruption of the video buffer as it animates to the "fade away" effect of the menu item. This might explain why it occurs more if a program that already interfaces with the video driver has crashed.
If your video card's latest drivers don't resolve it, you can mitigate it by turning off the animation (so the menu just flat-out disappears instead of fading away, so nothing gets stuck in the acceleration buffer). You could also disable hardware graphics acceleration but that'd be a big performance hit.
