Me too. The visual artifacts seems to appear mostly as the shift
switcher restores the layout post-switch. I have attached a screenshot
and also attach a very brief video for forensics.
Ubuntu 11.10 (Oneiric). ATI Radeon HD 5670 (PCIe, Saphire brand). Stock fglrx

I do not have the visual artifact problems with shift switcher on a similar
machine running 10.04 LTS, although it's video card is on the motherboard (ATI
Radeon HD 4200 on Asus M4A785TD-V motherboard). That machine also uses
official Ubuntu fglrx driver.
