First place to look would be at what you do to reproduce it. You could always leave 'top' running with a 0.5 or 1 second refresh in a terminal window, point some sort of video camera at the screen, and after you've reproduced it go back and look at the video frame-by-frame until you find the 'top' refresh(es) that happened during the high load.
