wayland + systemd + kde + screenshare + 'loop->recurse > 0' failed at ../pipewire/src/pipewire/thread-loop.c:426 pw_thread_loop_wait()

Symptoms

  • Firefox - Google Meet | Zoom - can't share screen.
  • Chromium - Google Meet | Zoom - can share only tab, and not windows or desktop.
  • Slack - Share Screen - gray pop-up without any options to select.
  • Obs - Screen Capture (Pipewire) option is not available.
  • 'loop->recurse > 0' failed at ../pipewire/src/pipewire/thread-loop.c:... pw_thread_loop_wait()

Troubleshooting

For some reasons, I noticed that WAYLAND_DISPLAY & XDG_CURRENT_DESKTOP are not set in the shell env, which might point to the login manager / systemd not setting the values correctly.
