Ok, this is pretty interesting...

I tried out the Xubuntu Live CD, out of curiousity, and noticed that the "slow drawing" problem did not exist. I checked the xorg.conf that was being used; it was using "nv".

So, I thought maybe the issue had been resolved. I downloaded a daily build of the regular Ubuntu Live CD. The problem still existed for plain-old Ubuntu.

Then, I switched back to the "nv" driver on my regular installation (I was using the proprietary "nvidia" because the problem did not exist with that). The problem still existed. So, I installed xubuntu/xfce packages on this installation, rebooted, and logged into an Xfce session => no slowness. Log out, log into GNOME => slowness.

I certainly thought this problem was probably at the X level, but now I have no idea. Perhaps it has to do with the window manager used by GNOME vs. Xfce?
