Test for Brecht: this line makes drawing buttons fine.
However note:

- redraws on lines 3107 and 3024 don't do anything
- tooltip timer is messing with redraws too, if you
have tooltips on, it continuously sends redraws.
- I would code tooltip to reset on any mouse move,
and only start timer when mouse is still completely.
That would make them appear much more quietly.
