Hi, @mrserb, thanks for the review. Your idea is awesome and I've tried to implement it. It contains some copied code from `sun.java2d` but I can't import necessary methods without adding it to dependencies. 

But the issue with different scale factors on multi-display configuration is still present, frame size scaling seems to be stuck at primary display's scale factor. `jaccesibilityinspector` shows correctly scaled bounds, may it be an issue with NVDA?
