Bug Description
It appears that graphical snaps cant be used over ssh, due to authentication problems with X.
$ which notes
/snap/bin/notes
$ notes
X11 connection rejected because of wrong authentication.
QXcbConnection: Could not connect to display localhost:11.0
Aborted (core dumped)

I can confirm this. Steps to reproduce:
In a vm:
$ sudo snap install notes
$ which notes
/snap/bin/notes
$ notes
(it launches)
Close notes then from the host:
$ ssh -X vm
$ notes
X11 connection rejected because of wrong authentication.
QXcbConnection: Could not connect to display localhost:10.0
Aborted (core dumped)
There are no security policy denials. I suspect this has something to do with the private /tmp and the hidden X directories, but would need an X expert to confirm.
