My unity becomes extremely slow after pressing ALT for the new program menu HUD. I rather think that's the problem, and not ALT-TAB. This problem has been ocurring for months now, so i reinstalled 12.10 via wubi an hour ago and encountered the same problems. Installing Gnome 3 gave even more bugs, so I'll try to keep Unity without using the program menu HUD.
I don't seem to get CPU spikes, although my desktop doesn't update the screen while loading the starter menu. Changing workspace or program is as fast as ever.
