Comment 16 for bug 282631

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Karmic Koala. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/. Thanks again and we appreciate your help.

Also if you can still reproduce with 9.04 or 9.10 please name the applications you are seeing this problem with. It may still happen with Firefox, Thunderbird, and legacy applications that do not use _NET_WM_SYNC_REQUEST to let compiz know when they have finished drawing and are ready to be displayed. It should, however, not be happening at all for GTK+ apps.
