I'm also experiencing this problem with nvidia drivers after 173, but only in the terminal. Doesn't matter which one. I tried gnome-terminal, xterm, konsole. But I noticed two things which may be useful to track it down:
1. For me it only occurs in single-head mode. As soon as I start my X-Server with a second display attached I have no screen update problems.
2. I noticed that the problem does not occur when a compiz animation is played. So enabling the benchmark window fixes the problem. Currently I use the Paint Fire feature of Compiz to workaround the bug when I'm in single-head mode. Usually I put the fire into the trash bin. ;-)
