Not the original commenter but, it... has a certain look to it. It's not something that can be totally solved by the OS or any scaling algorithm because fundamentally you have to deal with rendering fractional portions of a pixel to a physical screen where there is no such thing as a fractional pixel. It just always looks different, and IMO worse, than integer scaling.

You have to trade off distortions for bluriness and you can't avoid both of those artifacts at the same time. The higher your pixel ppi, the less noticeable any scaling artifacts will be though.
