> Jamie@, please check the comment in mouse_cursor_monitor_linux.cc#34. Tomas@ here helped to contribute screen capture function on Wayland. One fact is the mouse cursor capture is part of pipewire screen capture. As I recall, Remoting wants screen capture alone and will handle cursor by itself. So I'd like to know the how Remoting can work with this on Wayland. Please take a look.

The cursor is part of the stream as of now, but we have plans to add it as metadata to the PipeWire stream. I created flatpak/xdg-desktop-portal#234 to track the issue upstream.
