Apparently, this fix is primarily for Kubuntu users, so I don't know if this would benefit any Ubuntu users. I've noticed that when using KDE 4.1 or 4.2 betas, I get this nasty looking video garbage upon opening programs (even when I minimize/unminimize). This mostly happens with GTK related apps like Firefox. A custom patch to xorg was causing the trouble. Here's a snippet of what Martin Gräßlin said on his blog:
Good news to all Kubuntu and Fedora users. The cause for the video garbage (http://bugs.kde.org/show_bug.cgi?id=170462) appearing whenever a new window is opened has been discovered. A custom patch to xorg is causing the trouble. Now we can only hope that the distributions will provide updates for xorg without this patch.
A fix has been made available. Someone commented on Martin's blog saying that the patch was probably necessary for something and the removal of the patch could cause compositing to suffer. I haven't noticed anything wrong (I'm using an Intel chipset), but your mileage may vary. If you're using the new Nvidia beta drivers, you probably won't need this. If you would like to try and see if this fix works for you, simply add this PPA to your sources.list and upgrade:
deb http://ppa.launchpad.net/adamspain/ubuntu intrepid main
