Existing issue?

• I checked the existing issues

What happened?

Expected vs actual result:

The digit "8" is broken at font-weight 200 and 300, starting at a certain font size. Later, I discovered that the capital letter 'Q' was also broken in some font-weights!!!

Steps to reproduce:

1. Take a device with 2400*1080 resolution and Android 14 OS. (Samsung sm-a528b)
2. Go to Settings -> Display -> Display size and text -> Turn on the switcher "Bold text"
3. Run the following code:

import 'package:flutter/material.dart';
import 'package:google_fonts/google_fonts.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        textTheme: GoogleFonts.montserratTextTheme(),
        useMaterial3: true,
      ),
      home: Scaffold(
        appBar: AppBar(
          backgroundColor: Theme.of(context).colorScheme.inversePrimary,
          title: const Text("Montserrat Font Test Page"),
        ),
        body: Column(
          crossAxisAlignment: CrossAxisAlignment.center,
          children: <Widget>[
            const SizedBox(height: 50),
            const Text('w200, fontSize22:'),
            Text(
              'abcdefghijklmnopqQrstuvwxyz 1234567890',
              style: GoogleFonts.montserrat(fontWeight: FontWeight.w200, fontSize: 22),
              textAlign: TextAlign.center,
            ),
            const SizedBox(height: 20),
            const Text('w200, fontSize23 and above:'),
            Text(
              'abcdefghijklmnopqQrstuvwxyz 1234567890',
              style: GoogleFonts.montserrat(fontWeight: FontWeight.w200, fontSize: 23),
              textAlign: TextAlign.center,
            ),
            const SizedBox(height: 50),
            const Text('w300, fontSize15:'),
            Text(
              'abcdefghijklmnopqQrstuvwxyz 1234567890',
              style: GoogleFonts.montserrat(fontWeight: FontWeight.w300, fontSize: 15),
              textAlign: TextAlign.center,
            ),
            const SizedBox(height: 20),
            const Text('w300, fontSize16 and above:'),
            Text(
              'abcdefghijklmnopqQrstuvwxyz 1234567890',
              style: GoogleFonts.montserrat(fontWeight: FontWeight.w300, fontSize: 16),
              textAlign: TextAlign.center,
            ),
            const SizedBox(height: 20),
            const Text('w300, fontSize32 and above:'),
            Text(
              'abcdefghijklmnopqQrstuvwxyz 1234567890',
              style: GoogleFonts.montserrat(fontWeight: FontWeight.w300, fontSize: 32),
              textAlign: TextAlign.center,
            ),
          ],
        ),
      ),
    );
  }
}
