It gives me a headache. How could anyone look at it and think it doesn't need to change?

Apple has used this kind of blurry resizing animation in the past. For example, circa macOS 10.14 Mojave resizing windows in Split View would have the same effect: https://youtu.be/KDDMUxBtnkI

current view transition stack on ios was built for static transition between two well know layouts, like portrait to landscape rotation change. i would like live reflow too but i suspect 99% of existing apps aren’t ready to reflow at 120hz when they’ve been written around tween(start layout, end layout) style for decades
