>From what I've seen when things get really slow, it's redrawing too many
times and out of order.  IE, change notebook pages somewhere.  It first
draws the new page directly over the first, then redraws things a few
times until it's finally proper.  Raster or someone more GTK+ savvy want
to look at this, this is becoming an issue that needs some attention.  It
may actually be in GTK+ itself and in the less CPU/mem intensive themes it
doesn't show up.
