I'm using sway (wlroots + xdg-desktop-portal-wlr). Sharing the whole screen works. I have tried using chrome (stable and unstable) and OBS. OBS uses pipewire to capture (which I believe in turn talks wayland xdg-desktop-portal). I think chromium works the same way (I have the chrome flag "enable-webrtc-pipewire-capturer" turned on). There doesn't seem to be a way to share a single specific window. There is so much half-cocked or old information out there it is hard to find the right place to look. At the end of the day I'm not sure if xdg-desktop-portal, wlroots, or pipewire need to be improved.
