Description

Calling Window::set_cursor_visible hides or shows the cursor. On Linux Wayland (GNOME 42) though, this doesn't work once you've clicked the window (at least) once.

Demo code

I've composed a demo to reproduce it here: https://git.sr.ht/~tobtobxx/winit-wayland-mouse-demo

Behavior

1. Compile & Run this code.
2. Correct behaviour: C hides and shows the cursor.
3. Click anywhare inside the window.
4. Incorrect behaviour: C doesn't work anymore.
5. Moving the mouse outside the window restores the correct behaviour.

(the hotkey C just toggles the call to set_cursor_visible: source.)
