Hello, I have been using manjaro as the main system for a few months now, and I like it a lot, but there is a problem, and that is that in the wayland session, screen sharing does not work correctly, this happens in all applications when screen sharing.
Obviously, the applications must support screen sharing on wayland with pipewire. As an example on chrome you need to enable this flag:
chrome://flags/#enable-webrtc-pipewire-capturer and Firefox supports it out-of-the-box, but still there are many programs which relay on xorg and there you can only switch to pure xorg at the moment.
Maybe have look at this section of the archwiki: PipeWire - ArchWiki
