X11 doesn't repaint on resize.

[richard-uk1]

If you resize the window, it doesn't repaint until some other trigger (e.g. mouse over a button).

Needs repro - I've only seen it on my machine so far. Might be an issue with my setup, might not.

Do you have an example showing this behavior? I modified wgpu-triangle to remove the painting from the idle callback and the schedule_paint from the paint callback. That way, it no longer repaints repeatedly. But I still get paint calls when resizing.
