WindowChrome and TextOptions.TextFormattingMode="Display"

Hello! I've created a simple NET 4.5 project with XAML describing window:

<Window x:Class="WpfApplication4.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:shell="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        Title="MainWindow" Height="350" Width="525" TextOptions.TextFormattingMode="Display"><!--<shell:WindowChrome.WindowChrome><WindowChrome /></shell:WindowChrome.WindowChrome>--><Grid><TextBlock FontSize="15" HorizontalAlignment="Center" VerticalAlignment="Center">Hello, world!</TextBlock></Grid></Window>

If WindowChrome is disabled, text "Hello world!" displays in normal way (like in .NET 4.0 with "display" TextOptions.TextFormattingMode). But if you uncomment the lines with WindowChrome, text becomes blurry as it was in .NET 3.5. Setting TextOptions.TextFormattingMode directly on textblock does not help.

Is there a way to use Window Chrome with "display" text formatting mode?

Thank you.
