Here is the mail from Lindsay Mathieson about the Xorg bug that
causing the video garbage. I haven't tried the Xorg from the PPA
archive mention but will do that soon.

Good news to all Kubuntu and Fedora users. The cause for the video garbage
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. If you don't want to wait
that long and you are a Kubuntu user just add the following ppa to your
sources.list and upgrade your system:

deb http://ppa.launchpad.net/adamspain/ubuntu intrepid main

The interesting thing is that NVIDIA knew about this patch for at least one
month and started to work around it in their drivers. That's great as it shows
that they care about KDE and want to improve the KDE experience. The bad is
that they did not communicate that a custom patch to xorg is responsible for
the problem. Neither in KDE's nor in Ubuntu's bug report there is a comment
from NVIDIA. And that's sad. With a little bit more communication the problem
would have been solved much earlier.
