--- Comment #8 from Noel Grandin <noelgrandin at gmail.com> ---
There are a couple of potential issues I have identified:

(1) Drawing bitmaps with alpha is very expensive because of our weird split
color/alpha stuff. Fixing that is a way off, unfortunately

(2) We seem to be doing a complete redraw, instead of a partial one. That might
be easier to fix
