linux-drm-syncobj-v1: new protocol (!90) · Merge requests · wayland / wayland-protocols · GitLab

Since nvidia drivers do not properly implement implicit sync, this protocol not existing is the root cause of flickering with nvidia graphics on Wayland. This MR being merged means that Wayland might finally be usable with nvidia graphics with the next driver release.

EDIT: Nvidia dev posted that support is planned in the 555 driver, with beta release planned for May 15: https://github.com/NVIDIA/egl-wayland/pull/104#issuecomment-2010292221

AFAIK we still need this merge request here for it to actually affect 99% of games, because they all run with Xwayland, right? https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/967

Yes, but that's bound to be merged quickly, the protocol itself was the main holdup from what I understand.

Currently yes, tho Wine has gotten pretty far with Wayland support, so it wouldn't be too surprising to see Wine Wayland be useable for gaming in the next year or two.

We also need support for the new protocol in Nvidia's driver. Support will be available in driver 555, the beta of which will be released on May 15. So there's still some time to wait until it's fully fixed.
