I can confirm that it shows the behaviour described in the report in an up-to-date version of Ubuntu but not on the version as distributed on the live CD.
I tried to play around with downgrading packages an I could narrow it down to the packages compiz, compiz-core, compiz-gnome and compiz-plugins. Version 1:0.9.4+bzr20110415-0ubuntu2 of all of those packages works while 1:0.9.4+bzr20110606-0ubuntu1~natty2 does not. Unfortunately I couldn't downgrade them one at a time without breaking my setup to pin it down to one package
