The built-in double buffering allocates and frees a backing buffer the size of the expose for every expose event. I imagine your program is spending a lot of time doing this. I suppose the gtk buffer could also somehow not be in fast memory, giving you slow offscreen - onscreen copies. You'd need to do some timing.
