During a screen-share with https://github.com/brave/brave-browser/issues/17159 I noticed that Wayland is not triggering idle events. @aseren any ideas?

I only test official packages.

Where do you test them? I suggest Ubuntu 21.04 or Fedora 34 which default to use Wayland. Should be the same also on Gnome 40 in openSUSE Tumbleweed.
