Performance Issues with useNativeDriver in React Native 0.74.1 of New Arch: Comparing Animation Smoothness and FlatList Scrolling #44514

Open Hao-yiwen opened 4 months ago

Hao-yiwen commented 4 months ago

Description

In my React Native 0.74.1 app using the new architecture, when there are complex animations on a page, the animations display smoothly and the FlatList scrolls fluidly if I set useNativeDriver=false. However, when I set useNativeDriver=true, both the page animations and FlatList scrolling become choppy.

Steps to reproduce

  1. yarn
  2. npm run android

Why use useNativeDriver:false will make animated greatly,and useNativeDriver:true lead to animations and FlatList scrolling become choppy.This is really a strange thing.
