EditText box in TLHC handles resize and offset changes poorly #139230
Description
Is there an existing issue for this?
- I have searched the existing issues
- I have read the guide to filing a bug
Steps to reproduce
Filing this issue coz comments are disabled on the original one: #112712
We thought we found a way to use TLHC as a substitute for HC when wrapping a native textfield.
The solution suggested by @johnmccutchan (see here #112712 (comment))
indeed resolves the issue related to Magnifier lense, but a new issue originated as a consequence of that fix.
Basically, due to that override, the surface gets rendered with some delay and the platform view bumps when its position is changed (in our case the inputted text bumps when a new line is added).
Please do not discontinue HC as long as a fix for this is found. We've no alternative to it and we've also invested serious money/time on this.
Expected results
We would love to use TLHC but texture-rendering must be as smooth as with HC in the above described scenario.
Actual results
Platform View bumps when its position is changed on the scene.

The plugin uses TLHC and issue is reproducible
https://github.com/collinjackson/flutter-native-text-input/blob/1ef42d30462d97a3fafc856e356af83e106fe6b6/lib/flutter_native_text_input.dart#L334
Fork the plugin and change TLHC to HC to see that no issue occurs with HC.
Screenshots or Video
Bumping with TLHC:
note: this is a low res recording, issue is way more visible on the device.
