I got a new clue. I always disable nautilus for drawing my desktop (I don't use the desktop at all, since I got my beloved Unity ;) ). Now I reenabled it and it seems to solve the bug (maybe work around it since there's always a window left to draw?). I will keep you updated if the problem is really gone.
