I've always thought this was a cool idea. It's obviously been on the minds of Wayland protocol developers since the beginning, otherwise it wouldn't be possible!
I thought it was the other way around, X11 has supported multiple cursor since 2009 and Wayland didn't add support for it since toolkit developers weren't making use of it anyway.
Enabling in X works via:
xinput list # find second mouse id
xinput create-master second
xinput reattach <mouse-id> "second pointer"
Works great for clicking, but keyboard doesn't work in some applications when enabled. Dragging windows might attach them to the wrong cursor and other issues. Playing around with xinput can also crash some apps (libgdk-3 here) or leave you in a state without a keyboard or mouse.
Which desktop are you running where you can't figure out how to take a screenshot? Maybe some of the more tech-savvy folks here at HN can help you figure it out.
Since you edited your post I'll rephrase my question: Which desktop are you running where you can't figure out how to share your screen? Maybe some of the more tech-savvy folks here at HN can help you figure it out.
The fact you're griping about implementation details like pipewire makes me think you also tried micromanaging your env and broke something. If you use a fresh install and leave everything default, I'm sure it would work for you like it does for everyone else. I use KDE too btw.
