My point was more that rendering a few widgets at 60+ FPS is nothing for anything with a GPU, and everything has a GPU these days.
Anyway, something like this only needs to paint when states change or animations are running. That's an easy optimization to make here if it doesn't do it already. And games don't even bother with it, they repaint all UI even if it doesn't change.
