Bug#857228: Wayland vs X Windows

[Barak A. Pearlmutter]

Additional bit of info: when using the above Gnome keybinding for F12,
and when guake is set up to make the window visible on the screen the
mouse is on, guake doesn't notice that the mouse has switched to a
different screen should such motion have occurred entirely within a
Wayland window. Presumably for the same reason xeyes stops tracking
the mouse while the mouse is inside a Wayland window.
