It is excellent to see explicit sync. It is now is GNOME, KDE, XWayland, and Mesa. We just need the NVIDIA driver that supports it and that is coming soon I believe.

Most users will not see this until the fall distribution releases unfortunately. Rolling releases will be proving it all out soon though so it should be in good shape for the masses by year end.

Having these basic Wayland issues addressed and equalizing the experience between NVIDIA and other GPU hardware is a big win for everybody.
