Description

Reproduction steps: Apply a ScaleTransform to the ContentControl in the MainWindow of the demo app.

<ContentControl Content="{Binding ElementName=DemoItemsListBox, Path=SelectedItem.Content}">
    <ContentControl.LayoutTransform>
        <ScaleTransform ScaleX="1.3" ScaleY="1.3" />
    </ContentControl.LayoutTransform>
</ContentControl>

The problem can be observed with most of the controls that have fine lines. ComboBox and TextBox both use the Underline control, and Slider is another obvious one. The issue is that the rendered thickness of these lines is inconsistent.

This problem is typically resolved with the UseLayoutRounding and SnapToDevicePixels

The "fix" for this may be partially or fully in the demo application, in which case those changes should be documented here.
