TextInput multiline is jumpy and flaky when pressing new line

See original GitHub issue

Description

When you set mutline to true and enter/delete new lines, the scrolling is really flaky. Notice that this app was instantiated with npx react-native init myapp --template react-native-template-typescript

Steps to reproduce

import { TextInput } from 'react-native';

<TextInput
  style={{
    borderWidth: 1,
    borderColor: '#000'
  }}
  multiline
/>

Adding scrollEnabled={false} will somehow fix the issue but:

it’s not viable if you need the scrolling to be enabled.
It only fixes it for iOS, Android will still have a problem especially when delete new lines fast as seen in the video above.

oh, this has been around for years. yes it’s a regular text input that flickers in a very basic scenario so user can tell for sure if the app was made using RN)) the problem seems to be due to lack of space to render the string, or some like that, so I made a wrapper that measures the size of text and sets a min height (+some extra actually) for the input. Not perfect, bu now I’m using it.
