Comment 10 for bug 665546

If I may add, I'm using the native driver as well. I have the same native proprietary versions on two installations on the same box (I have one root partition for Lucid and one for Maverick, both mount the same /home). I've had this issue with all native driver versions I tried on Maverick (260.19.06, 256.53) but not on Lucid. So this "feature" is distinct to Maverick and is probably an issue with Compiz and not with the drivers.

Another small thing I can add: my Maverick installation is a clean one, not an upgrade from Lucid. This issue happens with both the account previously created by Lucid and with one created with Maverick (meaning, it's absolutely clean, so it's definitely not an upgrade issue).
