I don't think it's the high DPI screens themselves that cause this on Windows, rather the fonts have changed.

I'm pretty sure they used to be bit mapped, or had excellent hinting. Now that high dpi is common, maybe they figured that wasn't needed anymore. And indeed, on my 24", 4k monitor at "200%", windows is pretty sharp if I start it that way. If I change it while running, it becomes a shit-show. But when running at 100% on a FHD 14" laptop, sharpness is clearly lacking.

Regarding the Linux situation, yes, it's subjectively better on that same laptop. But it depends a lot on the fonts used. Some are a blurry / rainbowy mess. However, on Linux, I run everything at 100% and just zoom as needed if the text is too small (say on the above 24" screen).
