Desktop corruption on X600 with compiz
Since RHEL 6.2 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.
Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
don't think we'll fix this now.
I expect its due to the X600 have some coordinate limit and compiz not respecting it.
