it uses fyne.io, which supports wayland as of version 2.5.
and it also says that it runs without those runtime dependencies, except that the experience will be degraded. so the question is how degraded, and what will it take to fix that?
The compositor external dependency was really just an experiment and we replaced it already.
You can still turn of compositing but it does offer better speed for tabbing around windows and also means you can make each transparent independently :).
The new default is that background windows become slightly transparent.
compositing is not the issue but as others have mentioned dependency on X11 is. i look forward to be able to try it when it works with wayland. but don't let us pressure you. it will be ready when it's ready. not earlier.
