Comment 3 for bug 1066209

You're actually reporting two bugs so I'm making this about one of them. Please report the other elsewhere ("When moving windows with the mouse, the movement is smooth as long as the window does not go under the launcher.")

I think the primary issue here with the slowness with extra monitors is bug 1064834, which slows down proportionally to the desktop size. I'm testing on an identical HP Folio 13 and it's nice and fast with no monitor plugged in.

Maybe we should just say this bug is incomplete until bug 1064834 is Fix Released. Then if the problem persists, this can be treated separately.
