Does Glamorous Toolkit work for you? It's pharo with a different rust based GUI stack, and some batteries included for making custom inspector views and such. I don't have a high DPI display so I'm not completely confident, but my understanding is that their rust based GUI works fine with high DPI.

The one thing I've found google's models to be the best at is proofreading text in non-english languages. Probably because I imagine they have the most training data for it as Google probably has the most complete archive of the internet.
