+Subject: [PATCH] xsettings: don't use the xsettings watch function functionality
+
+The "watch" function functionality in xsettings-client.c is designed
+for setups like GDK where filters are per-window. If we are going
+to pass all events to _clutter_xsettings_client_process_event()
+anyways, we can just pass in NULL for watch.
+
+This avoids a nasty infinite loop where an event would get processed
+triggering removing a filter and adding a new filter, which would
+immediately run and remove a filter and add another and so on
+ad-infinitum.
