Please see problem in video. I don't know how to otherwise describe it.
I know this is probably a CrossFire problem, since disabling CrossFire or switching games to windowed fixes it, but I'd like to get CrossFire working with fullscreen games. My experience has been that fullscreen games are usually screwed up right from the start, but sometimes they start up and run ok until I Alt+Tab (as shown in the video).
Any help is appreciated. I've googled a ton and come up empty so far.

Turns out this problem was caused by a bad CrossFire bridge. Got a replacement for $5.50 on eBay, and now I can play games fullscreen and Alt+Tab without any issues.
