Sharing in Wayland Works Only The First Time

[Comara]

Currently using Arch Linux with Wayland.  With the latest zoom installed (6.6.0), using pipewire for sharing.  The first time I try to share a screen or window, it works fine.  If I stop sharing and try to share again, it only shares a completely black window or screen.  

Immediately after I stop sharing the first time, I get the following messages in ~/.zoom/logs/zoom_stdout_stderr.log

*** pw_stream_set_active called from wrong context, check thread and locking: Operation not permitted
*** impl_ext_end_proxy called from wrong context, check thread and locking: Operation not permitted
'this->recurse > 0' failed at ../pipewire/src/pipewire/thread-loop.c:62 do_unlock()

I cannot figure out if this is a zoom problem or a pipewire problem.

Everything works fine in X11.

It's a zoom problem - if you quit zoom and restart, it works again. Once.

I have the same issue, having to close zoom/re-join a meeting should not be necessary to screen share again.

One way to fix this particular problem is to edit ~/.config/zoomus.conf and change the line xwayland=true to false.

This will cause several other issues including one where it will crash zoom if you try to stop a cloud recording.

What I've done now instead to make life better and not have to use X11 is to switch to using the Zoom browser app only.  I'm using the plugin Xoom Redirector in chrome so that whenever I click on my zoom meetings it launches in the browser instead of the local app.  This is a good fix until Zoom can figure out the issues with their Linux client.

I'm running into this problem on Arch as well, though restarting Zoom doesn't fix the issue. The only reliable way I've found is to kill zoom, xdg-* processes, and pipewire. Others report gutting pipewire for pulseaudio fixed things, so pipewire+xdg-portal seem to be mostly the issue here as this affects teams the same way, but Arch+KDE doesn't let me remove pipewire for depenencies anymore.

I'm getting very similar results in Pop_OS 22.04 using either Cosmic or Gnome/Wayland as my desktop.

Zoom 6.6.0 and Pipewire 1.4.2-1pop1~1750269419~24.04~e495013.

I can turn screen sharing on and off in OBS, so I'm guessing its a zoom issue.

I'm able to share in Chrome only. Firefox doesn't work due to https://community.zoom.com/t5/Zoom-Meetings/Can-t-share-my-screen-on-firefox/m-p/99766.

Google Meet works in both browsers, as does Slack (Flatpak).

Same story on Fedora 43 (GNOME 49) and CachyOS with GNOME shell, where X11 doesn't exist. I also have the same problem on Fedora 42, no matter what settings I choose (or config I edit in zoomus.conf). Auto, Pipewire, XWayland, doesn't seem to matter. First screen share works fine, subsequent screen shares either result in a black screen, or crash the app, or crash GNOME shell entirely.

Version 6.6.11 (6052)

Using the official .rpm download on Fedora and the pacman package on Arch. The unofficial Flatpak doesn't work any better.

 Happy to provide the full output privately if Zoom support wants to reach out.
