Confirmed; I'm also seeing this on a Dell Inspiron 1420 running latest Hardy with Compiz turned on.
00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller [8086:2a02] (rev 0c) (prog-if 00 [VGA controller])
Also, it's not just yelp (although that reproduces the issue most reliably), but can occur on alt-tabbing between gnome terminal windows, opening new terminals, on tooltips, etc. although these cases seem more intermittent and harder to reproduce.
