Yes, it pops up on my desktop as well. And occasionally when I watch movies in the Quicktime player.
 
Odd, it's obviously not a display problem, as it is a screen shot.
 
Yes seems like a software problem.
Does it disappear when you drag another window over the desktop?

No, I can "hide" it if I put something over it. Its really odd. My friend says it's from overheating.
