Should all be in place. Even nvidia driver support. It’s one of the rare cases where I actually support nvidia on a technical level, that is, having explicit sync is good. I can also understand that they didn’t feel like implementing proper implicit sync (hence all the tearing etc) when it’s a technically inferior solution.

OTOH, they shouldn’t have bloody waited until now to get this through. Had they not ignored wayland for a literal decade this all could’ve been resolved before it became an issue for end-users.
