This does happen on my Intel i810 card. Since it's not radeon specific, I changed the summary.
** Summary changed: - Some windows do not render with "Desktop Effects" enabled on radeon + Some windows do not render with "Desktop Effects" enabled -- Some windows do not render with "Desktop Effects" enabled https://launchpad.net/bugs/89189 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
