Comment 12 for bug 372345

If anyone is still interested.

I was going to C&P the link, but didn't get the C part, apparently.

www.x.org's bug site directed me to bugzilla.

Apparently this is a regression from an earlier version of Xorg.

The bug was reopened very recently with

Priority: High
Severity: Major

It's not Jaunty or Compiz related. It's a bug in the latest Xorg.
