Zoom client starts, but fonts are all missing
I first thought this was a Zoom issue as it happened directly after updating the snap. However, they seem sure it's a Wayland problem. It does work just fine in when I switch away from Wayland to a default Ubuntu session (which I assume is Xorg)
I've attached a GIF to show it starting up with the missing text, and below that zoom-terminal.log in case it's useful.
I'll reproduce the output from the debug steps the Zoom team asked for in this ticket, you can see the conversation here: https://github.com/ogra1/zoom-snap/issues/31
$ snap version
