Limit to DrawVieportWires method?

Hi,

i was wondering if someone else ever ran into this issue:
I am drawing boxes to the viewport using override DrawViewportWires.
it works great, but if i scale the amount of boxes, i consistently hit a limit at about 170 boxes.
when i reach over 170 boxes, i get visual errors.
the lines start to go everywhere (see screenshot)
the blue wires are not supposed to be there.

i have checked if this is a bounding box issue, but that is not the case.
Do i need to update/empty some sort of display cache that is overflowing?
I have tried the same with lines, but i hit the same limit at about 170 boxes
this is a snippet from my code:

any ideas would be appreciated

   public override void DrawViewportWires(IGH_PreviewArgs args)  
   {
       if (WorldStorage.World == null) return; //early return.. does not draw anything

       var query = new QueryDescription().WithAll<RowLine>();
       WorldStorage.World.ParallelQuery(in query, (ref RowLine row) => { 
           args.Display.DrawLine(new Line(row.Start, row.End), System.Drawing.Color.MediumBlue, 3);
       });

       var query2 = new QueryDescription().WithAll<Box>();
       WorldStorage.World.ParallelQuery(in query2, (ref Box box) =>
       {
           Point3d[] pts = box.GetCorners();
           Line[] lines = new Line[8];
           lines[0] = new Line(pts[0], pts[1]);
           lines[1] = new Line(pts[1], pts[2]);
           lines[2] = new Line(pts[2], pts[3]);
           lines[3] = new Line(pts[3], pts[4]);
           lines[4] = new Line(pts[4], pts[5]);
           lines[5] = new Line(pts[5], pts[6]);
           lines[6] = new Line(pts[6], pts[7]);
           lines[7] = new Line(pts[7], pts[0]);

           foreach (var line in lines) args.Display.DrawLine(line, System.Drawing.Color.Green);

//gives visual errors at over 170 boxes

           args.Display.DrawBox(box, System.Drawing.Color.LightSkyBlue, 3); //gives visual errors at over 170 boxes
           
           args.Display.DrawBrepWires(box.ToBrep(), System.Drawing.Color.Red,-1); //this does not work for me... : System.AccessViolationException: 'Attempted to read or write protected memory. This is often an indication that other memory is corrupt.'
       });

   }
