Verschwommen Adorner WPF XAML

Question

Ich kann nicht für das Leben von mir dieses heraus, die gleiche Steuer Vorlage ich ein verschwommenes Adorner auf ein Element in meinem Panel erhalten:

Control Template:

<ControlTemplate x:Key="validationErrorTemplateBubble" > 
<DockPanel > 
    <Grid DockPanel.Dock="Bottom" Margin="10,0,0,0" > 
     <Grid.Effect> 
      <DropShadowEffect ShadowDepth="2" Direction="315" /> 
     </Grid.Effect> 
     <Grid.RowDefinitions> 
      <RowDefinition Height="*"/> 
      <RowDefinition Height="Auto"/> 
      <RowDefinition Height="Auto"/> 
     </Grid.RowDefinitions> 

     <Border Grid.Row="1" BorderBrush="Gray" BorderThickness="1" CornerRadius="5" Margin="0,-1.6,0,0"> 
      <Border.Background> 
       <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"> 
        <GradientStop Color="#FFE7E8F1" Offset="1"/> 
        <GradientStop Color="White"/> 
        <GradientStop Color="#FFF3F4F6" Offset="0.472"/> 
       </LinearGradientBrush> 
      </Border.Background> 

      <Grid> 
       <WrapPanel VerticalAlignment="Center" Margin="5,5,10,5"> 
        <Image Source="/Sesam;component/Modules/Images/wrongsmall.png" Height="15" Width="15" /> 
        <TextBlock Foreground="Red" FontSize="12" Margin="5,0,0,0" Text="{Binding ElementName=ErrorAdorner, Path=AdornedElement.(Validation.Errors).CurrentItem.ErrorContent}" /> 
       </WrapPanel> 
       <ContentPresenter Margin="5" Grid.Column="1" Grid.Row="1"/> 
      </Grid> 
     </Border> 
     <Path Data="M306.375,133.125L306.375,100.875L335.75,133.25" Stroke="Gray" Height="15" Fill="White" StrokeThickness="1" Stretch="Uniform" Margin="10,0,0,0" HorizontalAlignment="Left" VerticalAlignment="Center"/> 
    </Grid> 
    <AdornedElementPlaceholder x:Name="ErrorAdorner" /> 
</DockPanel> 

Nicht Blury Textbox Code:

<TextBox BorderThickness="0" VerticalAlignment="Center" Width="150" Padding="3" Margin="8,0,0,0" Foreground="{StaticResource myDarkBlue}" Text="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListView}}, Path=DataContext.encTypeValidation, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}" Validation.ErrorTemplate="{StaticResource validationErrorTemplateBubble}" HorizontalAlignment="Left" > 
<TextBox.Style> 
    <Style TargetType="{x:Type TextBox}"> 
     <Setter Property="Visibility" Value="Collapsed" /> 
     <Style.Triggers> 
      <MultiDataTrigger> 
       <MultiDataTrigger.Conditions> 
        <Condition Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListViewItem}}, Path=IsSelected}" Value="True" /> 
        <Condition Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListView}}, Path=DataContext.editClicked}" Value="True" /> 
       </MultiDataTrigger.Conditions> 
       <Setter Property="Visibility" Value="Visible" /> 
      </MultiDataTrigger> 
     </Style.Triggers> 
    </Style> 
</TextBox.Style> 

Verschwommen TextBox Code:

<Grid> 
    <WrapPanel> 
     <TextBox x:Name="tbox" Text="{Binding encTypeValidation, Mode=OneWayToSource, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}" Foreground="{StaticResource myTextBoxColor}" Validation.ErrorTemplate="{StaticResource validationErrorTemplateBubble}" PreviewMouseDown="tbox_PreviewMouseDown" Width="200" > 
      <TextBox.InputBindings> 
       <MouseBinding Gesture="LeftClick" Command="{Binding addBoxClicked}" /> 
      </TextBox.InputBindings> 
     </TextBox> 
    </WrapPanel> 
</Grid> 

Etwas über die Art und Weise es macht, die erste (nicht blury) innerhalb eines "ListViewItem" Control Template, das andere ein Usercontrol ist ..

Irgendwelche Ideen?

FIXED

behoben durch Hinzufügen UseLayoutRounding = "True", um das heißt Eltern Steuerung: Content!

Danke Aybe!

 <Grid Grid.Row="2" Background="{StaticResource myLightGrey}" > 
     <Border BorderBrush="{StaticResource myLightGrey}" BorderThickness="0,1,1,0"> 
      <ContentControl x:Name="AddPanel" VerticalAlignment="Center" HorizontalAlignment="Center" UseLayoutRounding="True"/> 
     </Border> 
    </Grid>

Hinzufügen UseLayoutRounding = "True", um den übergeordneten Container Steuerung löst das Rendering-Problem.
