Bubbles Screensaver Extremely Fast?

i was at a store yesterday, and an hp computer (windows 7 home premium, no sp1) was showing the bubbles screensaver, but they were moving across the screen extremely fast. here's a Internet video that i found that's showing exactly what it was doing: how to make it run like this on purpose? i figured that, if you leave it like this for a long time, it'll eventually go insane. i left my computer on overnight (12 hours) to see if i would wake up to the bubbles going crazy, but they weren't doing anything different than they normally do.i've already seen the registry tweaks page, but there's nothing that adjusts the speed, so i'm assuming that it's just a random bug. supposedly it happens in both vista (including sp1) and windows 7 (not sure if it does this on sp1).
