I tried on a older PC also (P4-based Celeron 2.0 GHz + integrated i845 graphics) and the problem is much more pronounced: moving a window over another one cause the bottom window to be almost fully greyed. Removing the "inset" text-rendering propriety significantly reduce the problem, and using a simpler theme (eg: Clearlooks, Mist, etc.) result in a even less pronounced gray trail (and lower CPU usage).
Hi, thank you for your support.
