The spec currently says that the newest window gets the screen...since users can alt-tab (or whatever) between them, this means the user can control which one they want to deal with at any given moment.

The intent is that multiple fullscreen windows--which I expect to be rare, but possible--can coexist, but I'm okay with whatever people agree is appropriate behavior for managing them.

To be clear, KWin (or krandr?) is getting an XRRScreenChangeNotifyEvent, and then resizing windows in response to that, and not the various application windows responding directly to this event. Is that right?
