I wonder, what is the deal with the render scaling on iPhone 7/8 Plus? iPhone 6s Plus did not appear to have any sort of scaling going on, it was all just antialiased. On iPhone 7/8 Plus you can see the effect of the scaling on screen zoom button in the Camera app and also in the YouTube app on the pause buttons. The lines are not incredibly crisp. This only happens with some UI elements and never with text.....so what gives?
