Tauri is the exact same problem, just done a bit more cleanly.
The problem is the evolutionary dead end that - hopefully - is web framework based "desktop" apps. There is already a framework for desktop apps, and unless you're still used to those, you wouldn't notice just how slow any web framework is by comparison. It's mostly the user interactions, that small but noticably delay on every interaction, every click, every type, everything. Funnily enough, my actual web browser (Firefox) shows one of the shortest delays when typing into web pages like this compared to all the "native apps" I got installed that are just web pages, too.
Tauri is an improvement. To the problem. It's not a solution.
