I've just tested 21.10 and can reproduce the bug in Firefox there. It
appears the cause is Firefox version 93 in Ubuntu 21.10, whereas Ubuntu
22.04 has Firefox 94. So here's how to fix it in Ubuntu 21.10:
snap remove firefox
snap install firefox --candidate
Chrome/Chromium will need a different fix but it doesn't even officially
enable Wayland support yet.

Bug description:
Freshly installed Ubuntu 21.10, screen sharing does not work with any
browser, tested the following options:
- Firefox snap
- Firefox deb
- Chromium snap
- Chromium flatpak
Steps to reproduce:
1. Go to
https://www.webrtc-experiment.com/Pluginfree-Screen-Sharing/#7325517390736006
2. Select to share the whole desktop in the xdg-desktop-portal
3. Notice the orange screen share indicator in Gnome-Shell but actually
nothing is shared in the browser.
This should be handled high priority since this is a critical feature
during the pandemic.
Filed against ubuntu-meta since I don't know exactly which package to
blame, whether it's pipewire, xdg-desktop portal or some problem
directely with mutter / gnome-shell, please reassign accordingly.
