    I just noticed that even on a RadDiagram with no Shapes there appears to be very small black spot.
    This is most visible when you set the Background of the RadDiagram to White and turn off the grid visibility.
    You may need to zoom quite a way into the diagram to see this.  If you do, it appears as a Black Circle.

    Here is how I am creating my empty RadDiagram in code behind:
       backgroundColor is Colors.White
       isEditingEnabled is false
    private RadDiagram CreateDiagram(Color backgroundColor, bool isEditingEnabled)
        var diagram = new RadDiagram
            IsBackgroundSurfaceVisible = false,
            Background = new SolidColorBrush(backgroundColor),
            IsPanEnabled = false,
            IsZoomEnabled = false,
            AllowCopy = false,
            AllowCut = false,
            AllowDelete = false,
            AllowDrop = false,
            ActiveTool = MouseTool.PointerTool,
            AllowPaste = false,
            IsDraggingEnabled = isEditingEnabled,
            IsResizingEnabled = isEditingEnabled,
            IsRotationEnabled = false,
            IsConnectorsManipulationEnabled = isEditingEnabled,
            IsManipulationAdornerVisible = isEditingEnabled,
            IsManipulationEnabled = isEditingEnabled,
            SelectionMode = isEditingEnabled ? SelectionMode.Single : SelectionMode.None,
            IsSnapToGridEnabled = false,
            IsSnapToItemsEnabled = false,
        DiagramAnimations.SetIsZoomAnimationEnabled(diagram, false);
        ScrollViewer.SetHorizontalScrollBarVisibility(diagram, ScrollBarVisibility.Hidden);
        ScrollViewer.SetVerticalScrollBarVisibility(diagram, ScrollBarVisibility.Hidden);
        return diagram;

    Hello Alan,

    We can confirm that this behavior of the RadDiagram framework was a bug. However, it is already fixed and the fix is available in our latest internal build. Can you please download it from your account and give it a try.
