Note that I specifically asked for :1

$ xpra list
Found the following xpra sessions:
/run/user/1000/xpra:
	LIVE session at :1
	LIVE session at :2
	LIVE session at :3
	LIVE session at :4
/run/xpra:
	LIVE session at :1
	LIVE session at :2
	LIVE session at :3
	LIVE session at :4

I think both of these issues have a common cause: ssh://user@ip/x is not enough to pinpoint to a display number somehow anymore.
Furthermore, there is no warning / issue coming up to the user's side.
