Comment 7 for bug 149377

Also experiencing this problem using xrandr and TwinView on a Nvidia GeForce FX 5200. In the attached screenshot the top panel has just been dragged from the right monitor to the left. Observe the "ghost" effects on the right-hand monitor. Also observe that the background of the panels is misaligned with the desktop itself. This occurs regardless of where the panels are placed.
