説明
Description
Following the discussions in https://github.com/facebook/react-native/issues/54497 and https://github.com/software-mansion/react-native-screens/issues/3392, I was able to reproduce it using a custom native component with view recycling disabled.
I'm opening this issue as a follow-up for further investigation with a reproduction in the reproducer app.
Steps to reproduce
- Clone https://github.com/t0maboro/Repro3392# and use the latest version from
mainbranch - Run the application on iOS
- Navigate forward -> back -> forward
- Then toggle the Switch component - the liquid glass has disappeared

調査の方向性
github.com/t0maboro/Repro3392 にある必須の reproducer から始め、issues 54497 と react-native-screens 3392 にリンクされている議論を確認してください。iOS アプリを実行し、navigate-forward/back/forward のシーケンスを再現してから、Switch を切り替えて liquid glass エフェクトを比較します。親で view recycling が無効になっている場合でもエフェクトが表示され続ければ完了です。
