Does this mean that if the fullscreen surface has some transparent area, 
the user will be able to see the fact that the panels are removed from 
the screen?

I would expect the panels to remain visible below the fullscreen 
surface, so the user could click on them if there are transparent areas 
in the fullscreen. This scheme means a client can force the panels to 
vanish by putting up a transparent fullscreen surface.

That sounds extremely obnoxious. Especially if the panel obscures the 
object being clicked to bring up the popup menu! I would change it to 
not show the panels if there is *any* fullscreen surface.
