Sure, I am not saying it's new, nor am I saying it's a problem. Obviously, the text rendering (without zooming in), is very crisp on my retina display (MacbookPro 15'' 2019, Touch Bar). I am looking at it with a magnifying glass. I am just curious, how do they do that given the fact that they first render it into a backing store and then scale it down by some very odd factor, which is definitely not 2 or 1 or some other similar "easy" case. How is that I am not seeing any resampling artefacts. Bear in mind that text rendering is a pretty tricky business with all those hinting, and kernings, and serifs, and what not.
