Text mask displays incorrectly using dynamic display

I am using the GraphicTracker to display icons and labels. Using the IMask interface I can add a text mask background so the text is easier to read. Using the "ESRI.ArcGIS.Display.esriMaskStyle.esriMSHalo" type works great. The halo completely covers the background of the text. When I enable dynamic display (for performance) it causes each character in the text label to be surrounded by its own halo and separated by some small amount of space. This looks terrible and takes up quite a bit more space to display. I have tried many things without success. The attached image shows what the labels look like with dynamic display off and on.

Is there any way to get the display to be the same with Dynamic Display turned on?

Here is the code to create the textsymbol:

    Public Function CreateTextMask() As ESRI.ArcGIS.Display.ITextSymbol

        Dim SimpleFill As ESRI.ArcGIS.Display.ISimpleFillSymbol = New ESRI.ArcGIS.Display.SimpleFillSymbol
        Dim Mask As ESRI.ArcGIS.Display.IMask
        Dim Text As ESRI.ArcGIS.Display.ISimpleTextSymbol = New ESRI.ArcGIS.Display.TextSymbol
        Dim TextColor As ESRI.ArcGIS.Display.IRgbColor = New ESRI.ArcGIS.Display.RgbColor
        Dim MaskColor As ESRI.ArcGIS.Display.IRgbColor = New ESRI.ArcGIS.Display.RgbColor
        Dim Font As stdole.IFontDisp

        Font = New stdole.StdFont
        With Font
            Font.Name = "Arial"
            Font.Bold = True
            Font.Size = 10
        End With

        With TextColor
            .Red = 0
            .Green = 0
            .Blue = 0
        End With

        With MaskColor
            .Red = 100
            .Green = 200
            .Blue = 0
        End With

        Mask = Text

        SimpleFill.Color = MaskColor
        SimpleFill.Style = ESRI.ArcGIS.Display.esriSimpleFillStyle.esriSFSSolid
        SimpleFill.Outline = Nothing

        Mask.MaskSymbol = SimpleFill
        Mask.MaskSize = 3
        Mask.MaskStyle = ESRI.ArcGIS.Display.esriMaskStyle.esriMSHalo

        Text.Font = Font
        Text.Color = TextColor

        Text = Mask

        Return Text

    End Function

Turns out to be a bug.
