Don't tie frame callbacks to actor painting, as it may end up in situations where we miss sending frame callbacks when we should have. An example of this is when a surface is partially off screen, and then reports damage that is fully off screen. When this happen, we are likely not to repaint anything, thus we won't send any frame callbacks even though it's "suitable" for rendering again, as the surface is not on a separate workspace or fully obscured.
