ControlPaint.DrawReversibleFrame - How am I supposed to erase drawn rectangle?

Consider the following code:

Dim recSelection As Rectangle?
Dim pntDown As Point?
Dim pntMove As Point?

Protected Overrides Sub OnMouseDown(e As Windows.Forms.MouseEventArgs)
    MyBase.OnMouseDown(e)

    pntDown = Me.PointToScreen(New Point(e.X, e.Y))
    pntMove = pntDown
End Sub

Protected Overrides Sub OnMouseUp(e As Windows.Forms.MouseEventArgs)
    If Me.recSelection.HasValue Then
        ControlPaint.DrawReversibleFrame(recSelection.Value, Me.BackColor, FrameStyle.Dashed)
    End If

    pntDown = Nothing
    pntMove = Nothing
    recSelection = Nothing

    MyBase.OnMouseUp(e)
End Sub

Protected Overrides Sub OnMouseMove(e As Windows.Forms.MouseEventArgs)
    MyBase.OnMouseMove(e)

    If pntDown.HasValue Then
        If recSelection.HasValue Then
            ControlPaint.DrawReversibleFrame(recSelection.Value, Me.BackColor, FrameStyle.Dashed)
        End If

        pntMove = Me.PointToScreen(New Point(Math.Max(Math.Min(e.X, Me.ClientSize.Width), 0), Math.Max(Math.Min(e.Y, Me.ClientSize.Height), 0)))

        recSelection = GetRectangle(pntDown, pntMove)

        ControlPaint.DrawReversibleFrame(Me.recSelection.Value, Me.BackColor, FrameStyle.Dashed)
    End If
End Sub

Private Function GetRectangle(pointA As Point, pointB As Point) As Rectangle
    Dim intLeft As Integer = Math.Min(pointA.X, pointB.X)
    Dim intTop As Integer = Math.Min(pointA.Y, pointB.Y)

    Dim intRight As Integer = Math.Max(pointA.X, pointB.X)
    Dim intBottom As Integer = Math.Max(pointA.Y, pointB.Y)

    Return Rectangle.FromLTRB(intLeft, intTop, intRight, intBottom)
End Function

Basically I want to draw a selection rectangle over a control and its children. In MSDN documentation, it says that to erase the rectangle, I should recall the DrawReversibleFrame method with the same parameters used to draw it in the first place.

Unfortunately, in my case that doesn't seem to work. The previous selection rectangle remains painted over the control. At one point I can end up having multiple selection rectangles accumulating:

(not the actual screenshot, I used MS Paint to reproduce the effect)

What am I doing wrong?

UPDATE:

I tried the very same code shown in the documentation and the behavior is the exact same! Might have something to do with my specific display settings. Also I'm using Windows 8.1. Could that be the issue? I'll try deploying on another system tomorrow.
