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.

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.
