I’m using React Native and the package react-native-prevent-screenshot-ios-android to block screenshots in my app.

It works fine in LTR languages (English, etc.), but when the device language is Arabic (RTL), a very strange UI bug happens:

❗ Problem

Whenever I call:

enableSecureView();

on screen focus, and:

disableSecureView();

n blur, the entire iOS app layout shrinks from the bottom. Each time I navigate into/out of the screen, the UI becomes smaller and smaller.

This does NOT happen in LTR mode — only when RTL layout is active.

Example behavior:

Enter screen → enableSecureView() → layout slightly shrinks

Leave screen → disableSecureView()

Enter again → shrinks more

Repeat → UI becomes unusable

❗ Additional Issue

If I try to patch the iOS native file to fix the shrinking:

The layout bug is fixed

BUT screenshot blocking no longer works on iOS (because the library uses a specific secureTextEntry + layer re-parenting hack)

So I cannot get both:

RTL layout working

iOS screenshot blocking
