### Your Environment

Start by reproducing the issue with the shown multiline TextInput on Android 14 using the reported React Native and react-native-paper versions, then trace the TextInput component's Android text and IME handling. Confirm whether the duplication occurs through the component or the native input path. Done means entering a Vietnamese word and pressing space leaves it unchanged.
