I've just upgraded to Ubuntu 12.04 on HP Envy 14 and found a rather interesting bug. When I switch between workspaces using keyboard shortcuts, for example moving down to Workspace 3 from Workspace 1, workspace switcher is shown (as seen on below screenshot). It stays there until I hit escape key.
After debugging, the problem only happens when I change shortcut keys to
direction. With default
direction, everything is OK.
I've searched but haven't found this problem reported before, I'm also not sure this is called workspace switcher :) Can you please let me know what to search for, are there any logs which might have some related information?
