I am setting up a laptop for a friend with Ubuntu 10.10. I turned on fancy visual effects and the "desktop cube" plugin as well. When I rotate the cube every window and even the wallpaper gets dark and desaturated. I tried looking into other plugins, even turning them off, other Gnome options, and I couldn't figure out why this fading happens. I've set up various computers with Ubuntu before but I have never seen such a problem.
How could I turn the fading off and keep the visual effects?
