This will need some further investigation as to why it's not working if we want to see this fixed.

My guess is that the GStreamer PipeWire integration isn't working all that well, since it works with every client in use: WebRTC, OBS, KPipeWire.

Please if you find anything that KWin is doing wrong, reopen this ticket and I'll look into it.
