iOS-only rendering failure in React Native – parts cease rendering over time (react-native-gifted-charts) [closed]

I’m seeing a progressive rendering failure on iOS in a React Native app that does not reproduce on Android.

Signs

• Sure screens cease rendering fully after a number of navigations

• react-native-gifted-charts line chart behaviour:

  • Initially renders accurately

  • Then renders partially

  • Ultimately doesn’t render in any respect

• Android works constantly with the identical code and knowledge

Traits

• No JS errors

• No native crash

• No purple display screen

• Navigation nonetheless works

• Structure containers mount, however kids don’t paint

• Happens after repeated display screen mounts/unmounts

Stack

• React Native: 0.79.6

• iOS: 18.7.3

• react-native-gifted-charts: ^1.4.64

• Hermes: enabled

• New structure: enabled

• React Navigation with NavigationContainer[! The chart is partially rendered]
