We need to coordinate with MetaCompositor during pre-paint so that we have control over whether MetaLater callbacks happen first, or the MetaCompositor pre-paint logic. In order to do so, make MetaLater listen to a new signal "pre-paint" on MetaCompositor, that is called MetaCompositors own pre-paint handling. This fixes an issue where the top window actor was calculated after the MetaCompositor pre-paint handling, meaning the top actor being painted was out-of-date. https://gitlab.gnome.org/GNOME/mutter/merge_requests/798
