Text wiggles when stretching the scroll view on Android running Impeller #177492
Closed as duplicate of#167795
Description
Steps to reproduce
- A scroll view contains many text items.
- On Android device, the user stretches the scroll view when they reach the top or the bottom.
- Text slight wiggles when stretched.
I found that it was only reproducible on Impeller.
Device: Samsung Galaxy A06 (SM A065F)
Android: 15
Expected results
Text should not wiggle from left and right. It should smoothly stretch.
Actual results
Text wiggles from left and right.

const TextWiggleBugPage({super.key});

),
body: ListView.builder(
itemCount: 50,
itemBuilder: (context, index) {
return ListTile(
title: Text('Item $index'),
subtitle: const Text(
'This is a subtitle that might wiggle when scrolling. '
'Let\'s see if it behaves correctly without any issues.',
),
);
},
),
);
}
}
