I have experienced the same problems as described in the first post on a
lenovo Thinkpad W500 (with an ATI FireGL graphics card, incorrectly
identified as a Radeon HD3650) running ubuntu 9.04.
Enabling the restricted ATI driver causes the creation and maximisation
of windows to be really slow (100% cpu usage) and lead to system
instability (simultaneously running firefox, glxgears and a terminal
made x.org unresponsive; I needed a hard reset).
After disabling the restricted ATI driver the problems disappeared.
I have experienced this problem after upgrading from xubuntu 8.10 (which
did not seem to have this problem) to xubuntu 9.04 and after a fresh (no
manual changes to xorg.conf or other configuration files) install of
ubuntu 9.04.
If more people with recent ATI graphics hardware are also experiencing
this problem (together with system instability), it might be a good idea
to increase the severity of this bug report since it seriously hampers
the `desktop experience'.
