Took another look at this patch. I noticed a few things. First, it doesn't build when screen-share and the RDP backend is enabled, because of the API changes in the first patch. The other thing is that if weston runs on top of a compositor that doesn't support the .frame event, it will fail to implement support on its own. In other words, if compositor-wayland runs on an older wl_seat, it needs to emit wl_pointer.frame events by itself. The same applies to screen-share. The RDP backend also wasn't updated to emit the new .frame event.
