[Bug 881031] [NEW] Alt-tab works only some of the time when using dual screen with separate X window.

[naranek]

Public bug reported:

The problem: Alt-tab opens the cover switcher about one out of three to
six times.

I tried setting the alt+tab shortcut to perform mute to see where the
problem is, and it worked perfectly. So it seems that the keystroke is
recorded, but cover switching isn't activated every time. I tried
disabling the effect (Effect for cover switching: None) but it doesn't
help.

This only happens when I have the dual screen set up using Separate X
screen. In Twinview clone mode alt-tab works perfectly.

I'm using a Nvidia GT 9600 card with proprietary drivers from ubuntu
repository.

This bug was present at 11.04 and followed thru to 11.10.
