Hello, yesterday I officially released Louvre v1.0.0, a C++ library designed for building Wayland compositors with a primary focus on ease of development. It provides a default method for handling protocols, input events, and rendering, which you can selectively and progressively override as required, allowing you to see a functional compositor from day 1.
It supports multi-GPU setups, multi-session (TTY switching), and offers various rendering options, including a scene and view system that automatically repaints only the damaged (changing) regions during a frame. Because it uses multiple threads, it can maintain a high FPS rate with v-sync enabled when rendering complex scenarios. In contrast, single-threaded compositors often experience a rapid drop in FPS, for example, from 60 to 30 fps, due to “dead times” while waiting for a screen vblank, leading to the skipping of frames.
The library is freely available, open source, thoroughly documented, includes examples, and features a detailed tutorial.
You can find it here: https://github.com/CuarzoSoftware/Louvre
I hope it proves useful for you. If you decide to use it and encounter any doubts or wish to contribute to its development, please don’t hesitate to reach out.
Greetings!

Wayland is already a lot nicer to use over X. Better gestures, better animations, better performance, and that’s if you use Wayland today, not in a year’s time.
Like I get why people are defensive over X but it literally isn’t being developed anymore - And if it’s really worth keeping over Wayland the time to get contributors to support it is passing quickly.
I agree with your overall sentiment with the caveat that 20 years will be closer to 5. Early adopters are enjoying Wayland only benefits today. For example, the Steam Deck just launched with HDR and mainline support for Linux gamers in general will not be far behind.
Also, the list of window managers being left behind is starting to look less appealing than the list of window managers that are Wayland only. Hyperland is probably already more popular than WindowMkaer. As GNOME and KDE go Wayland only, they will continue to add features that regular users will want. I see more announcements for new Wayland compositors than I do for new X window managers.
Another factor that gets missed is that the main dev support for X comes from Red Hat. RHEL9 is already Wayland based. When RHEL8 comes off support in 5 years, Red Hat will abandon X. How long will X stay viable after that?
As the number of X users dwindle, we will see toolkits drop support for X. GTK5 for example. 5 years may be too soon for that but I cannot see it taking 20 years.
Wayland being “valuable to most users” will come faster than you think.
