I think macOS applications feel like they have mostly updated to use the native resolution, so arbitrary scaling works great now. My comparative experience with a new Windows laptop is how I remember macOS felt when they first made high density screens many years ago: lots of render bugs all over, and every program has to be re-opened when I plug in an external screen to be usable at the new resolution
We should probably have nicer scaling algorithms that account for Moirés. Also, when you see a Moiré, that’s because you are scaling a bitmap that has periodic dithering. These should be more rare now, and a good opportunity to replace them with vector images with periodic patterns that are tuned for physical dimensions rather than pixel count.
