Rhino.Display.DisplayPipeline.DrawPoint() with PointStyle buggy?

i was playing around with the DrawPoint method of the DisplayPipeline in some project. When i set the PointStyle to any other value than “X”, the point gets translated on the viewport when zooming in or rotating the view.
Is it maybe some issue with the ClippingBox?

The example in the image is in the attached Grasshopper file:
