1. Create empty WPF project.
2. Use property CacheMode="BitmapCache" in MainWindow's Grid;
3. Show MainWindow on start application, then hide it. Show new MainWindow. You can use a code below. Additionally remove StartupUri in App.xaml
4. Press Ctrl + Alt + Del or Win + L and try to interact with showed window (resize, minimize) it should be broken now.

In App.xaml.cs OnStartup overrided method:
`var window1 = new MainWindow();
window1.Show();
await Task.Delay(1000);
window1.Hide();
var window2 = new MainWindow();
window2.Show();`
