I can confirm this as well, Ubuntu 10.04, x84, gnome-do 0.8.3.1. It's been happening for a while now, it seems, I just finally got around to looking it up. Killing gnome-do and restarting it appears to clear the problem up.
I'm tempted to say that this bug appears sometimes after waking from sleep, but I'm not entirely sure. I'll keep an eye out.
