bug#25887: 26.0.50; Exiting fullscreen

[Dani Moncayo]

I see this problem on Ubuntu GNOME[1], but not on MS-Windows[2].

Also, the problem disappears if I turn scroll-bar-mode off.

-------

Recipe from 'emacs -Q': <F11> <F11>

The Emacs frame should go fullscreen on the first command,
and go back to a normal (non-fullscreen) frame on the second
command.

Here, the second one does not seem to do anything at all (the frame
remains fullscreen). I have
to press <F11> a third time in order to exit fullscreen.
