Even if Windows/Linux do fractional scaling fine, integer scaling is still desirable if it’s an option. Under both I still run into programs that botch fractional scaling some way or another, and given the proclivity of programs on both platforms to be built with oddball UI toolkits I don’t expect that to ever really fully resolve itself.

It’s one of the chief complaints I have with one of my mostly otherwise good x86 laptops. The 1.5x scaling the display needs has been a pain point on multiple occasions.
