I think the current consensus is "that's hopeless, use Wayland instead".

Each toolkit will behave differently, in addition to the settings you've 
found. They'll each have their own environment variables or dynamic settings 
that configure the scaling that may be necessary.

And in my experience, there is no good solution when you have displays with 
significantly different DPI connected at the same time.
