Always force-track the cursor position (so that the X11 backend can keep it up to date), and if the cursor wasn't part of the sampled framebuffer when reading pixels into CPU memory, draw it in an extra pass using cairo after the fact. The cairo based cursor painting only happens on the X11 backend, as we otherwise inhibit the hw cursor. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1391
