Comment 100 for bug 772612

This happens for me too in Oneiric. I've been on Oneiric since October but I don't recall having this problem until the past month and now it's a daily occurrence. All I have to do is maximize a window, minimize it, then restore it again. The problem occurs whether the window is fully maximize (Alt-F10) or if it's just maximized to fill the desktop area (Ctrl-Alt-Numpad5).
