Comment 119 for bug 729979

It's not simple. 12.04 comes with compiz 0.9.7.6. So it is no wonder you can't reproduce the bug there. This bugreport is about the compiz versions that ship with Ubuntu and not stuff you compiled yourself. You should report those bugs in the launchpad for Compiz and not the launchpad for Ubuntu.

For 12.10: what do you mean with stable compiz release? I get a feeling you're (again) not talking about the compiz that comes with Ubuntu.
