    embedded-window: Set as app-paintable to workaround opaque region issues
    
    In specific cases, GTK+ does not have enough information to set a correct
    opaque region, in which the recommended fix is to set your window as
    app-paintable. In the tray icon case, the socket window was considered
    opaque but GTK+ as it had a solid window background, but it cannot have an
    opaque region set, as the plug isn't composited against the socket, but
    instead punches through the socket window.
