Miracle-WM Announced As A Wayland Compositor Built On Mir

[SViN]

Show me a current window manager or desktop environment using Arcan so that we can compare. Otherwise it's just fluff in the air and theoreticals.

There aren't that many because people focused on Wayland.
However that doesn't mean these are theoreticals. You can already see that they exist and work.
The video I posted is not some animation. Its a genuine desktop environment done using arcan. They have a VR desktop and a scrolling desktop too.
