Ok I was further playing and found out that you can use DrawingDraw for much faster performance. Basically this solves the problem imo.

Use the following piece of code in your Paint routine:

        DrawingDraw dd(GetSize());

        dd.DrawRect(GetSize(), White);
        dd.DrawLine(x,y,150,150,50,Blue);

        draw.DrawDrawing(0, 0, GetSize().cx, GetSize().cy, dd);

You can turn on backpainting for a flicker-free version, with a small performance hit.
