Do you think this bug will be fixed in the next maintenance release?

Otherwise can you give me a hint in which unit and procedure I have to look (approximately) to fix it?

You didn't answer the question concerning the 3D alignment bug?

The graphics extends beyond the Y axis (you can see that by loading the attached .tee file):

  IsoLinesChart.ClipPoints:=True;

1) De-activating the OpenGL renderer should automatically activate the normal GDI rendering again (like in all old versions) and not show an empty screen.

2) How can I programmatically (in code) switch the chart painting back to GDI (as a workarround)?

Uses TeeStore, TeCanvas;

procedure TForm1.Button1Click(Sender: TObject);
begin
  TeeOpenGL1.Active := not TeeOpenGL1.Active;
  if TeeOpenGL1.Active then
    Button1.Caption := 'OpenGL Active = True'
  else
  begin
    Button1.Caption := 'OpenGL Active = False';
    IsoLinesChart.Canvas:=TTeeCanvas3D.Create;
  end;

 IsoLinesChart.Repaint;
end;

This is a big problem, we going to release a new version of our SW package soon. And now it seems like I have to redo all modifications
and go back to a previous (working) TChart Version (8.06).....

Another question was why the graphics dissapears (the axes are still shown) when I switch to OpenGL mode?

procedure TForm1.Button1Click(Sender: TObject);
begin
  TeeOpenGL1.Active := not TeeOpenGL1.Active;
  if TeeOpenGL1.Active then
  begin
    IsoLinesChart.View3DOptions.ZoomFloat:=100;
    IsoLinesChart.View3D:=True;
    Button1.Caption := 'OpenGL Active = True'
  end
  else
  begin
    Button1.Caption := 'OpenGL Active = False';
    //Workaround
    //IsoLinesChart.Canvas:=TTeeCanvas3D.Create;
  end;

 IsoLinesChart.Draw;
end;
