We don't want sources that are no longer associated with a running application to stick around in the message tray. Message tray sources were removed when the associated application’s state changed to Shell.AppState.STOPPED . This caused sources for applications that were still running, but did not have any open windows to be removed. Instead, we should use the notification’s sender removal from DBus as an indicator for when to remove the associated source from the message tray. https://bugzilla.gnome.org/show_bug.cgi?id=645764
