CheckBox tick mirrored when changing FlowDirection - wpf

Question

O.S. : Microsoft Windows 8.1
Developing Application: Microsoft Visual Studio 2013 (WPF App development)
I have moved from Windows 7 to Windows 8.1 and now my old apps which i had developed in VS2012 have a weird manner. because my language is right-to-left, i use RightToLeft for FlowDirection. it was working fine as all text was showing on the left side of CheckBox but now the tick sign of CheckBox is mirrored like this:
the tick sign is not correct even in a right-to-left language. is this because O.S. or the VS2013 and how can i fix it? do i need to create a template? thanks.

Answer 1

I had the same problem, and this is the best solution i found. The path is what draws the tick, so just changing its flow direction back to LeftToRight makes it draw as you would expect.
<CheckBox Content="My Checkbox" FlowDirection="RightToLeft">
<CheckBox.Resources>
<Style TargetType="{x:Type Path}">
<Setter Property="FlowDirection" Value="LeftToRight"/>
</Style>
</CheckBox.Resources>
</CheckBox>

Answer 2

<Grid>
<Grid.Resources>
<Style x:Key="ArabicStyle" TargetType="{x:Type CheckBox}">
<Style.Resources>
<Style TargetType="{x:Type Path}">
<Setter Property="FlowDirection" Value="LeftToRight"/>
</Style>
</Style.Resources>
</Style>
</Grid.Resources>
<CheckBox Content="My Checkbox:" Style="{StaticResource ArabicStyle}"/>
</Grid>

Answer 3

When you want to use standard Checkbox Control, set FlowDirection of path to LeftToRight will work but if you create a custom template it doesn't work so Make a custom Style template for CheckBox like this and set FlowDirection of main Grid to LeftToRight" :
<Style TargetType="{x:Type CheckBox}">
<Setter Property="SnapsToDevicePixels" Value="true" />
<Setter Property="OverridesDefaultStyle" Value="true" />
<Setter Property="Height" Value="30" />
<Setter Property="FocusVisualStyle" Value="{DynamicResource MyFocusVisualStyte}" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type CheckBox}">
