Bug Description
When a window decorator is not in use, both the "application switcher" and "static application switcher" show corrupt previews (blank for windows with transparency; black for non-maximized windows, ok for the rest).
After two or three uses (use alt-tab to change window, let the dialog fade, then do it again) the screen freezes.
I've tested this on three machines:
The first machine (laptop) has an Intel video card, and the screen turns off, and /var/log/kernel.log shows the attached errors. A full power cycle in required to have the display work again (not even restaring via SSH works; the screen remains off).
The other computers have nvidia video, and simply freeze. I can SSH into it, kill compiz, and restart it [compiz] and it goes on running fine (except for the initial issue).
In this case, compiz spits out the following warning every time I alt-tab: "compiz (core) - Warn: failed to receive ConfigureNotify event on 0x600293".
I've just now discovered that enabling the "Show icon only" option for the "Static Application Switcher" plugin avoids these crashes/fixes; though an alt-tab with no preview is really sad (but a workaround for the meantime, nonetheless).
I can provide any other information that may be needed, or test any fixes/alternate builds/etc.

I can also reproduce this bug.
I just locked up my machine does it too, and had to reboot. this is a nasty bug.
Applications switcher has graphical artifacts, and once leaving the switcher sometimes windows like CCSM have artifacts in them, minimizing the window gets rid of the artifact.
