Does this need to SchedulePaint?

Not if we call this before we show the widget. Also, this is how the label works
(apparently they changed it, I'm sure it used to be different).

As far as I can tell, most methods which modify the appearance of the view call
SchedulePaint to ensure that it gets redrawn. Can you change this one to do so
as well? It may work in your scenario but others may call set_shadows after
showing and expect it to work.

I imagine label should be changed as well (may be implied by the size
invalidation) but that can be done later.

Okay, done.
