can you also paste the output of

snap info zoom-client

also, what desktop are you running ? (this was supposed to be fixed with a commit from november, somewhere around revision 120 and i can not reproduce it on a standard 20.04 GNOME install here)

I am using GNOME as a default desktop. If this can help, cat /etc/X11/default-display-manager shows: /usr/sbin/gdm3.

this was supposed to be fixed with a commit from november, somewhere around revision 120 and i can not reproduce it on a standard 20.04 GNOME install here

The system has just been installed, precisely on the 20th of Dec 2020. I have not been messing with any system related files, neither have I done anything with fonts. I know system has been updated at least once since then, automatically. I did not force it.

What may cause this problem, then?

Thanks

I found the issue. My problem was related to TexLive 2020, the LaTeX package. It turns out a font installed with the application: 09-texlive.conf which is a link to /path/to/.../texlive/2020/texmf-var/fonts/conf/texlive-fontconfig.conf is incompatible with the new version of fontconfig that is 2.13.1. I removed the file, rebuilt the cache:

rm -f ~/.config/fontconfig/*
sudo -f /var/cache/fontconfig/*
sudo fc-cache -rv

and everything seems to be working.
