The portal processes bind to the compositor that existed when they started; after a kwin
restart the stale instances point at a dead socket and RemoteDesktop/EIS input injection
times out ("EIS setup timed out"). Hit live: a fresh session streamed fine but ate no
mouse/keyboard until the portals were restarted.
