gnome-shell display garbled
as shown in the attached screenshot. Also while pointing mouse at the top left corner, the screen flickers like crazy.
This does not happen with unity-3d on the same machine, also it seems that the ati driver has nothing to do with it (because after this problem I tried to install the restricted driver, same symptom).
