This MR just got merged: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/19125
Which completes the tearing protocol: https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/65
So once the mesa update lands, XWayland titles should be able to tear under Wayland, at least on AMD GPUs. Nvidia will have to provide support in their drivers in the future.
Meanwhile, I’m still not able to achieve smooth, tear-free gameplay on No Man’s Sky on Wayland. Both on GNOME and KDE 🫤
I was surprised when I learned that some people want their tearing back 😆
