With gnome 42, mouse cursor input is locked quantized by the Hi-DPI scale.
This makes painting for e.g. not have such smooth input when the `scale` is above 1 (Hi-DPI).
This seems to be a bug/limitation in gnome-shell (mutter), since the same bug doesn't exist in river compositor for e.g.
- Running under `GNOME Shell 42.2`.
- rB9bed68de134c9cc5ff5295b95cc1bf0bae97b78a with `WITH_GHOST_WAYLAND=ON`.
- This doesn't impact tablet input.
