Wallpaper displaced after update

[Les Lamb]

After updating 11.10 beta 2 on Sept. 29, 2011, I restarted and upon logging in, the wallpaper on all four desktops is moved down and to the right. Also, when I restarted, update manager was open and appeared BEHIND the wallpaper. When I close an app, it remains open, but appears partially behind the wallpaper. The orange glow that normally appears around the active virtual desktop in expo view is also around the misplaced wallpaper of whatever desktop I am currently in.

Here is another screenshot of what happens when I close a program (in this case, Firefox). Notice how it is closed, but its ghost appears behind the wallpaper.
