The Chart ClipPoints property doesn't work correctly in OpenGL, so when you scroll series up, it disappears before reaching the rectangle bounds. Also, if you scroll down the series, this moves out of rectangle bounds.  The attached project reproduces the problem.

Here a simple code that reproduces the problem:

uses TeeGLCanvas, Chart, Series, TeeConst;

var Chart1: TChart;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Caption:=TeeMsg_Version;

  Chart1:=TChart.Create(Self);
  Chart1.Parent:=Self;
  Chart1.Align:=alClient;

  Chart1.View3D:=false;
  Chart1.Legend.Visible:=false;

  Chart1.Canvas:=TGLCanvas.Create;

  Chart1.AddSeries(TLineSeries).FillSampleValues;

  Chart1.OnDblClick:=Chart1DoubleClick;
end;

procedure TForm1.Chart1DoubleClick(Sender: TObject);
begin
  Chart1.View3D:=not Chart1.View3D;
end;
