Maybe the size of the thumb changes more often with emacs.  IIRC,
emacs calculates the thumb size based on the #(characters in the
window) / #(characters in the file) ratio, so just dragging the
cursor may change the size of the thumb.

If GTK repaints the entire scroll bar when the thumb size changes,
maybe that could explain the flicker.
