Who may have thought in 2004 that 20 years later you may have to use a specific language and a specific ui library to run gui on different platforms without 500mb runtime and it still stuttered. Why are we like this? It’s literally 66% more APIs that you need to support since then, everything else is already done. Take GDK/Cairo or Qt abstraction layers, integrate it with platform-specific smooth scrolling api and paint whatever widgets you want efficiently. Even proxying it to html-css would do the trick, although for a price.
