I have the same problem, also using the xorg ati driver. This was a problem in the clearlooks-cairo theme engine as well, before clearlooks was reverted to its pre-cairo version.
I have the problem on a Radeon 9200mobility, but I have never seen the problem on my desktop system which has an NVIDIA card. -- Glitched scrollbar https://launchpad.net/bugs/42317 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
