If I hold my finger on alt & right arrow, to cycle through tty's, every now and then the display breaks up, and the monitor goes way out of sync for a second or so before returning back to normal. This does need physical console access to do though, so I'm not concerned :) I doubt that it's harmful either, just.. strange.
