Text anti-aliasing broken in Flutter 3.3.0 #110738
Description
Text or Container border looks jagged on Android, normal on Apple.
Not all pages will be jagged, such as the following code, the comment Divider can be displayed normally.
Or modify the height of _Statistics to display normally. On my device height 10 or 86 reproduces the problem.
On my device this problem only occurs with scrollable components.

runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
