A "modern" compositor for X11, written in Rust and based on WGPU and Vulkan.
There really aren't many X compositors out there, and there are very few of those that are still maintained. Also, as far as I'm aware, none are written in Rust / using WGPU. Most are forks of the original compositor, xcompmgr, which is written in C.
Basically a test. Not usable at all yet.
