I have exactly the same problem with a nvidia 9600M GT in my laptop.
I seen it for the first time in jaunty (i was using nvidia 180 driver), but also in karmic with 185 driver I have the same problem.
I noticed that some landscapes (mars, moon, tree) works fine, others not (including the default one).
