it's seems that this problem is driver related and a dupe of this one:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/195051
so perhaps that will be a good idea to go to this bug for the ati driver:
http://bugs.freedesktop.org/show_bug.cgi?id=15096
There are no reaction from the devs right now but perhaps if a lot of people are expressing their concern to have this solve that will help.
