I wonder if this ties into why I'm baffled at the increasing trend of adding fake delays (f/ex "view transitions"). It's maddening to me. It's generally not a masking/performance delay either; I've recompiled a number of android apps for example to remove these sorts of things, and some actions that took an entire second to complete previously happen instantly after modification.
Have you tried disabling animations in the System Settings? Some apps respond to that.
