If you think it's one of the screensavers but don't know which one, then open up a bash shell and do a
for i in /usr/lib/xscreensaver/*; do echo $i; $i ; done
hitting control-c to break out of the screensaver when you think it's been cleared of any wrongdoing. They'll default to rendering in a window rather than the root window, but perhaps that'll be good enough to hit the bug (it also lets you see the name of the screensaver it just ran).
