Did some more testing and it turns out that when the desktop is in this state, hotplugging displays causes the session to crash back out to the login screen. So it's not as usable as I hoped in all cases, but this is still really weird.

The Unity desktop is much, much smoother after _toggling off_ "copy to texture" in compizconfig during a session. There don't seem to be any performance gains from starting up with it turned off; it has to be toggled mid-session.
