This happens to me as well.
X3100 video using the 'intel' driver.
using xrandr to rotate the display (any way, inverted, right or left) on my Fujitsu T4220 convertible causes artifacts to appear when windows are moved.
When 'xrandr -o normal' is run again , everything is fine.

I'm also not using Compiz at all.
I can post Xorg log if it helps.
