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!

      Yes (kinda), that is a screenshot of one of the example compositors I included called “louvre-views” which implements server side decorations for apps that support the XDG Decoration protocol.
