I am also seeing this problem after upgrading to the 10.04 beta on my Thinkpad x200s with an intel GM45 card.
Installing cpuburn and running burnP6 (from a terminal or ALT+F2 run dialog) causes it to happen more often. Just a quick flickering on the bottom half of the screen. This happens whether or not I'm running any gnome-terminals.
