linux-drm-syncobj-v1: new protocol (!90) · Merge requests · wayland / wayland-protocols · GitLab
gitlab.freedesktop.org
This is a new Linux explicit synchronization protocol based on DRM synchronization objects 1.

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

    I saw a comment from an nvidia dev somewhere that XWayland support is enough to resolve the flickering, but compositor support is needed for best performance.
