--- Comment #3 from Alexei neowall@yahoo.com 2010-11-03 09:00:45 PDT --- Alex, I'm also still getting this error on Radeon X1650.
$ lspci -nn | grep VGA 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV535 [Radeon X1650 Series] [1002:71c7] (rev 9e)
Running glxgears and resizing produces:
