Sometimes if I unlock Ubuntu and happen to have a window focused it will be partially off-screen with these orange circles holding white arrows on the window. My default assumption is that they're some sort of resizing/move function (given placement and style), but I can't seem to do anything with them or make them go away.
When this happens I can: Alt+Tab (and change focus but not bring the window in front of mozilla / hide mozilla) and Alt+F4 out of mozilla (but not give me back control - I'm stuck with the moving hand mouse). I can't seem to get back general control without a hard reboot (that is, no keyboard or mouse input is accepted).
How can I avoid this? Is there a key combination to get out of this mode? Or am I stuck closing Firefox every time I lock my computer?
I've tried using Alt+F8 and Alt+F7, but neither of those fixes the error. Using them normally also doesn't reproduce the orange circle white arrows thing I see when this breaks.
For reference I just updated to 11.10 two days ago and this problem never occurred before.
Edit: I've now had this happen with Skype replacing Firefox in all particulars.
Edit 2: And most recently it happened with Gedit. From what I can tell the only times it hasn't happened is when I'm focused on a workspace that is a) empty or b) covered by full screen something.
Edit 3: As far as I can tell this occurs for any application not in full screen mode, provided I have the workspace they are in active.
