Sounds like an interesting take. Is it public?

It will be public but I'm still working on it, its unusable yet (code rendering and painting works, but no feedback loop, no file format to save reviews, etc.): https://imgur.com/a/zpBpfco

The code is https://github.com/fschutt/azul/blob/fix/input-bugs-2026-09-... - the code is surprisingly readable, but the UI is very janky and I've only tested a bit on macOS so far. I'm still working on the UI framework, performance, etc.
