We did the tests over Windows and Linux.

This is just one condition about the behaviour for fullscreen surface. 
The client doesn't know it, or even leave that fullscreen status. In 
fact, It doesn't need to know it.

When the top-level of regular surfaces in compositor side is 
un-fullscreen, The focus of the compositor should be that un-fullscreen 
window. Once you click on that fullscreen surface or switch to it, you 
can go further to use the menubar.

You can use alt+table switch to that fullscreen surface. This can 
resolve your concern. :)
