Bug Description
GTK apps on Mir: Input focus is unreliable and sporadic. Background windows ignore input and/or focus switches apparently randomly.

$ GDK_BACKEND=mir mir_demo_server --launch gnome-mahjongg
Show the "Scores" - you can switch focus between this and the main window with Alt+` but doesn't respond to input.
