The "Force synchronisation between X and GLX" option solves the problem for me in Jaunty, but it doesn't work very well on Karmic. Now I have a big screen refresh problem when I minimize the aMSN window to tray (bug #465644). I tried enabling and disabling the "Force synchronisation between X and GLX" option without luck, as well as using other nvidia-glx versions.
