This
[Wu, Zhiwen] I think the transparent areas in the fullscreen just make under
surfaces visible but not let the input event deliver to them.
So user could not click on the panels even though they are visible.

[Wu, Zhiwen] Yes, but only when the fullscreen are on top. My concern is
that do fullscreen surface really need transparent areas to show panels?
