At least on a Nexus 9, running examples/widgets/pop_out_and_expand.dart , there are obvious seams in each corner of each box.

Chrome does a good job of this. We should dump their SkPictures to see what commands they use to get nice seams.

I'm going to guess that this is not longer an issue?

I don't think the code has changed since then, it seems unlikely it's been fixed.

Looks fixed

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  final String title;

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Container(
          padding: EdgeInsets.all(10),
          decoration: BoxDecoration(
              color: Colors.blue[700],
              border: Border.all(width: 9, color: Colors.red[700])),
          child: Text(
            'THIS IS COOOOOOOO0!!!!!!!',
            style: TextStyle(color: Colors.white),
          ),
        ),
      ),
    );
  }
}
