Another big tick in the box for switching over to Wayland from Xorg, with the release of XWayland 21.1.3. In the release announcement it was noted that it has no changes over the previous release candidate build.
With this release of XWayland, it brings in support for the latest NVIDIA 495.44 stable driver, released back in October where NVIDIA finally added support for the GBM API.
So what does this actually mean? In short: much better Wayland support. With this and the 470.57.02 release before it, that came with hardware accelerated OpenGL and Vulkan rendering on Xwayland, things are looking to be in a pretty good spot now. This is all needed, as when distributions make the full switch over to Wayland, you will still want your games and applications designed to run on Xorg to work fully and all this together should make the experience good.
It's been a very long road to get to full Wayland support but it looks like 2022 may be the year of Wayland. Especially so with the Valve Steam Deck releasing with SteamOS 3 that will also use gamescope, a Wayland compositor, in the main gaming session (not desktop mode).
