Thanks for the reply. I launched the live "CD" version of the daily build on the machine. The display was changed to a different monitor with "ordinary" 1280x1024 resolution. Sorry, it is not practical for me to repeat the old setup and rerun the test.
I see that the nouveau driver is indeed loaded on that machine, so this is an opportunity to try out the new version of the OS. I am yet to check whether the screen corruption would occur in this setting. But I am frustrated by the "flashy" animations of windows etc, which I suspect is due to compiz (I can see compiz process using lots of CPU). How do I disable this? Sorry this is OOT, but if you (@Christopher) can help, I may be able to test out some more without the flashy compiz stuff.

On random occasion, usually after unlocking a screen saver, the screen will look corrupt. Symptoms: 1) desktop background is always corrupted 2) Letters from some fonts would become garbled. To work around (1), I could restart nautilus. But for the other symptom, I don't know. Background: I originally installed this when I had a different external display (and I was using proprietary nvidia driver included in Ubuntu 10.04 LTS). The original resolution was 1600x1024. But with the higher resolution, the proprietary driver was not adequate (it would not even show anything beyond 1280x1024, I believe?), so I had to give it up and use the (apparently unstable) nouveau driver. Is this bug resolved somewhere else? If so I would like to know which version. Feel free to ask me more question.
