Unfortunately this is fairly common with ATI cards on Linux.  I had
the exact same issue with a Dell laptop a couple years ago.  I think
adding these lines to xorg.conf may have solved it though:

In ServerLayout:
        Option          "AIGLX" "true"

In Device:
        Option          "XAANoOffscreenPixmaps" "true"
        Option          "DRI"   "true"

I'll keep using it with these configs and see if it has really cured
the problem.
