[SOLVED] Broken browser-based screensharing

My KDE-based setup has been stable for many months if not years. I switched to Wayland many months ago and I use screensharing from Brave or Firefox on a daily basis.
Screensharing stopped working starting April 28th, 2025 and thus in any of the following browsers: Firefox 138.0.1-1, Chrome-Stable 136.0.7103.59-1, Chrome-Beta 136.0.7103.48-1, Brave 1.77.101-1.
When stuff likes this happens I usually switch back to an Xorg session but even in that case it wouldn't work.
I finally found a way to get screensharing to work by using Firefox Beta 139.0b2-1.
Opera 118.0.5461.60-1 seemed to be working at first but I could only share once  If I stop sharing then the screen stays live on the other side.

Has anyone seen such behavior lately?  BTW I tried to downgrade wayland-protocols since it was updated around that time but that didn't change anything.

Here is what I captured from CLI when launching screensharing:

Re: [SOLVED] Broken browser-based screensharing

Hi, I have exactly the same issue and I am also running KDE + Wayland. I tried Zen, Firefox and Brave, but all failed. Thanks to your post I can use Firefox Beta 139.0b2-1 to screenshare, which for me is an acceptable temporary solution. I noticed something that maybe could be helpful:

'loop->recurse > 0' failed at ../pipewire/src/pipewire/thread-loop.c:425 pw_thread_loop_wait()

appears with Firefox Beta 139.0b2-1 too, but only when I close the screenshare. In the case of Firefox standard and Brave, that log is printed immediately when trying to start the screenshare. Thanks again, you saved me today.

Re: [SOLVED] Broken browser-based screensharing

I'm glad my post helped someone. The timing was very bad for me as I had to attend some business meetings.

Today I updated Google Chrome Beta to version 137.0.7151.6-1, but it didn't work so well.

Re: [SOLVED] Broken browser-based screensharing

It's also still happening for me and stopped working around the same time.  I haven't tried firefox beta version you mentioned yet but the most recent chrome from aur is still broken with respect to this behavior.

Re: [SOLVED] Broken browser-based screensharing

Spent some time investigating this today and it turns out uninstalling and reinstalling the KDE Plasma plugin resolved the issue for me:

Re: [SOLVED] Broken browser-based screensharing

Thank you very much, @Redwood, for posting the solution.
I was puzzled today after updating Firefox to version 139.0 and finding the same issue, considering that Firefox 139 Beta was fine.

Re: [SOLVED] Broken browser-based screensharing

Removing the Plasma Integration Browser plugin solved it for me too under Chromium and Firefox.

Did someone report this issue upstream?

Re: [SOLVED] Broken browser-based screensharing

Thanks a lot, I had the exact same issue and completely forgot about the Plasma Integration Browser plugin. I removed it and it's now working very well
