I just updated to Android 12 and the new border-radius on nearly every UI element is beyond absurd. It actually looks like someone just discovered that CSS property, and instead of being told by a designer "that looks goofy and childlike, tone it down," they doubled the value and put it on even more elements.

My notifications pull-down fits about 3 useful notifications. The rest is whitespace and rounded corners 4 layers deep. It's horrible.
