ToggleButton doesn't show any state - wpf

Question

I've got the most simple application ever: single window with one single toggle button:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<ToggleButton Content="This is my ToggleButton" />
</Grid>
</Window>
When I now click on the toggle button, really nothing happens. When I setup event handler for Checked and Unchecked event, and then click the button, first the Checked and then Unchecked get fired. So the button seems to work correctly ...
I am compiling to .NET 4.5 and I am using Windows 8 RTM.
Is this behaviour related to the Windows 8 style of displaying buttons (no "3D" border)? Can anyone confirm?
UPDATE 1
I made up an image to show what I meant:
As you see, in Windows 8 "nothing happens" when clicking on the toggle button, it simply does not get "toggled".
This seems to be a bug, related to the windows 8 style of displaying buttons ...

A hotfix is avalible: http://support.microsoft.com/kb/2805222
See Issue #5 under WPF
Unfortunately it doesn't fix the problem for me :(

Answer 1

This is a confirmed defect in WPF. The workaround is to style the control accordingly, although a fix may be considered by the product group. To request a fix, please contact Microsoft Support.

Answer 2

For everybody who want some code to start off with, you can take the code I used to style my controls:
<Application.Resources>
<!-- Toogle button fix (includes custom button + toggle button style) -->
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="{StaticResource ButtonNormalBackground}"/>
<Setter Property="BorderBrush" Value="{StaticResource ButtonNormalBorder}"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Padding" Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border BorderThickness="1" BorderBrush="#FFA4A4A4">

<ContentPresenter x:Name="ContentPresenter_Content" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="false">
<Setter TargetName="Rectangle_Background" Property="Fill" Value="#f7f7f7"/>
