When run as a user (not daemon) the cursor is not visible

[AlanGriffiths]

Doesn't happen on Intel, doesn't happen when run as a daemon but seen on RPi400.

1. Log into a VT on a classic system
2. As the same user (on that VT or via ssh) run ubuntu-frame

Expect: cursor moves with mouse
Actual: cursor not visible

Note: this is probably confinement related as refreshing with --devmode gives the expected behaviour

Further note: I don't see this with mir-kiosk

Jeez, I've spent quite some time thinking something is wrong with my setup. I can reproduce it in VirtualBox with Ubuntu 22.04 when running ubuntu-frame as a daemon vs user. Also, it works with --devmode indeed.

There are a couple of deny actions in the journal:
