You’re mostly there, but the big issue now is their handling of Xwayland. nVidia also doesn’t expose VRR/GSync under Wayland (but an engineer remarked that it’s slated for the 545 series release on the nVidia Linux forums).
The most glaring issue currently that effectively blocks Wayland for nVidia users is the lack of implicit sync on their end, and the Xwayland developers refusal to merge nVidia’s proposed explicit sync method. This is oversimplifying but the short version is from nVidia “implicit sync is too slow, it architecturally conflicts with our driver forcing a comprehensive rewrite, and we don’t want to look bad with implicit sync’s performance”. The response from X devs boils down to “You weren’t there when we planned all this, implicit sync works fine, explicit sync won’t benefit how the Mesa drivers work so this would only be for your benefit, and you’ve been complete assholes”.
Neither side looks like it’s going to flinch, so getting Wine to run in Wayland is the only feasible solution for nVidia users. In an all-wayland environment with no applications running under Xwayland, Mutter and plasma-wayland run like a dream, it’s a great experience.
