Oh, and also there's this test program, mentioned in the issues: https://git.sr.ht/~tobtobxx/winit-wayland-mouse-demo. It demonstrates hiding the cursor (with C) and dragging the window (both require sending the Wayland compositor the "latest" serial. Both should work now on all Wayland implementations). |

Fixes #2273. The underlying method for hiding the cursor (setting its texuture to NULL) is wayland_client::protocol::wl_pointer::WlPointer::set_cursor(). This method expects a serial number of the last **enter** event. Right now, `latest_event` is any latest pointer event. It gets used by the call to set_cursor() and also to start_interactive_move(). While set_cursor() expects the latest enter event, start_interactive_move() expects the very latest serial from any event. Thus we need to track both. After this change, both serials are tracked and the appropriate is used in the call into smithay-client-toolkit. Tested on sway and gnome (on sway it already worked before the change).
