I also found this bug in up-to-date oneiric with compiz version 1:0.9.5.92+bzr2791-0ubuntu2
It seems to work better with a pause, but not consistently. Also if i release the mouse button very fast, i get the attached pic.
Btw, i remapped the key for screenshot to Super+Shift+Mouse so it doesn't conflict with Unity. That was the only change.
I'm on a new installation of oneiric with the old /home, but i already deleted all compiz and unity related config a few times after installation because of other problems.
