Opinion after 1 day of Liquid Glass and 1 day of “reduce transparency” enabled:
Liquid Glass is trash, but the other UI changes are quite good!
Enabling “reduce transparency” disables Liquid Glass in iOS 26 and macOS 26. It is a necessity for me because of my astigmatism.
The resulting flat aesthetic then reveals many thoughtful, incremental UI improvements.
It also reveals a bunch of cringe small margin and border issues, but still a net positive.
