I worked with the mutli-screen setup for half a day now without any
issues, after resetting Unity settings. Looks like the issue is fixed,
therefore I marked it invalid. If it occurs again, I'll re-open the
issue. Thanks for the support!

Title:
Graphical hangs on mouse display switch
Status in Unity:
Invalid
Status in “unity” package in Ubuntu:
Invalid
Bug description:
The issue I'm experiencing is really strange. It started after
upgrading to 12.04. The issue only occurs when my 2 externals monitors
are connected. I disabled the "display barriere" to achieve the
behaviour of 11.10. I also use "auto focus" on mouse over.
Ocassionally, typically when I move the mouse between displays, Unity
suddenly hangs, right after a display switch. There are several kinds
of hangs I can report, which seem to be slightly related to the amount
of action I perform on the desktop (mouse moving, window switching,
etc.):
- Unity does not re-draw, I need to move the mouse over broken content to let
it be redrawn
- The mouse hangs for 1-3 seconds and the system resumes its normal work mode
- The mouse hangs for longer, a switch to shell 1 and back to 7 fixes the
issue
- The mouse works but clicking on anything does not give a reaction
(switching shells helps)
- No reaction by the system, only hard reset fixes it
