Why is it that when I navigate from the first screen to the second screen, there is a white blink on the left side of the screen?

first screen code:

const Stack = createStackNavigator();

function MyStack() {
  return (

<Stack.Navigator
  screenOptions={{
    headerShown: false,
}}>
  <Stack.Screen name="Login" component={Login} />
  <Stack.Screen name="Cadastrar" component={Cadastrar} />
</Stack.Navigator>
);
}

export default function App() {
 return (
  <NavigationContainer>
    <MyStack />
  </NavigationContainer>
);
}

Second screen code:

const register = () => {
  navigation.navigate("Cadastrar")
}
