Can anybody else confirm this is not present in Quantal? It's a difficult-to-reproduce bug, and I'd hate to see it back when I upgrade. I think that this was introduced with the latest Unity patch which messed with ALT-TAB (a different bug was solved, where ALT-TAB switcher sometimes failed to appear), since I didn't notice it before the latest update and now I notice it all the time.
