Actually rather than duping to bug #428769 I'm going to just move this to compiz and let those guys decide if it's a dupe. Your symptoms are quite a bit different, and the hardware is different, and that case is for when the resolution == 2048 whereas yours is >2048.
One other question, are you doing anything to override compiz checks? Can you run `apport-collect 556631` - which should pick up the relevant compiz logs and config files for them to review?
