While I do enjoy a nice and smooth gpu-accelerated ui, I never use a gpu-ui framework for my own project for one simple reason: Almost none of them properly support accessibility.
Electron (and in general the web), despite its sluggishness has a very good support for accessibility. Most "traditional" native ui toolkit also do.
That would be my advice to anyone making a gpu-accelerated ui library in 2023: Try to support accessibility, and even better: make it a first class citizen.
