There is a wayland protocol called presentation-time that's supposed to provide precise timing information to clients, GNOME just merged support for it two days ago: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1484 https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1484 (AFAIK random clients should not really be using this though, the intent is for it to get used internally by the GL/Vulkan implementation)
