RenderOptions in Render() ignored when visual parent(s) have RenderOptions set in XAML

[AngryCarrot789]

I'm not sure why this behaviour is happening but this is my ControlTemplate:

<ControlTemplate>
    <Border x:Name="PART_ClipBorderRoot" BorderThickness="1,0"
            BorderBrush="{DynamicResource ABrush.Tone1.Border.Static}"
            UseLayoutRounding="False" RenderOptions.EdgeMode="Aliased">
        <Panel x:Name="PART_Panel" Margin="0,20,0,0">
            <ContentPresenter x:Name="PART_ContentPresenter"
                              HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
                              Content="{TemplateBinding Content}"
                              ContentTemplate="{TemplateBinding ContentTemplate}"
                              CornerRadius="{TemplateBinding CornerRadius}"
                              RecognizesAccessKey="True"
                              TextElement.Foreground="{TemplateBinding Foreground}"/>
            <a:AutomationSequenceEditorControl x:Name="PART_AutomationEditor" Margin="0,5"/>
        </Panel>
    </Border>
</ControlTemplate>

And in my AutomationSequenceEditorControl 's Render method I'm pushing render options with anti-aliasing onto the stack, but the pixels are not anti-aliased. Anyone know why this is happening?

This is what I currently get:

But if I remove the RenderOptions.EdgeMode from the Border, I get normal anti-aliasing except the control I've made now doesn't render quite right, I get weird sub pixel issues around the border:

Can you show code to demonstrate how you're pushing the new RenderOptions?

I can't see any issue on the border.

[AngryCarrot789]

The border is only rendered weird when I select the control, since the BorderThickness becomes 2. The code is literally just something like using var unused = ctx.PushRenderOpton(new RenderOptions() { EdgeMode = EdgeMode.Antialias })

New renderootions, that's it probably. Better to use the .WithXxx method

I get the exact same behaviour if I set the EdgeMode for AutomationSequenceEditorControl in the XAML too which I assume will use WithEdgeMode in the background
