View Capture Class ScaleScreenItems Property not working?

So I have created some text on screen using Render Text to Screen.

When I run the View Capture Plugin I made, the image looks like this however

The text on the screen are not scaled properly.

Here is my code:

            int scale = 2;
            var view_capture = new Rhino.Display.ViewCapture
                Width = view.ActiveViewport.Size.Width*scale,
                Height = view.ActiveViewport.Size.Height * scale,
                ScaleScreenItems = true,
                DrawAxes = false,
                DrawGrid = false,
                DrawGridAxes = false,
                TransparentBackground = false
