Finally found the culprit: an assertion is failing over on PipeWire:
'loop->recurse > 0' failed at ../pipewire/src/pipewire/thread-loop.c:426 pw_thread_loop_wait()
I also found that OBS can screenshare just fine. It seems like jumping from the "preview" to the actual screenshare on firefox/chromium is what causes the error. I filed a pipewire issue to see if the failed assertion can get us anywhere: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/3428
Ah, this is fixed in Firefox Beta 117.0b8, so it was clearly a problem on their side. I initially thought it was https://bugzilla.mozilla.org/show_bug.cgi?id=1841851, but updating regular firefox to 116.0.3 did not fix it. Either way, apologies for the noise, I was just frantically trying to debug the breakage :)
Nice. Glad you got it sorted.
What's really interesting is that Chromium's "share entire screen" preview works - I can see the small screen there after selecting it. But then, once I start the screenshare, nothing - just like on Firefox.
