The problem appears to be with NULL_BRUSH. A workaround for drawing a rectangle outline with openGL disabled is:

  n_ACSIL::s_GraphicsPen OutlinePen;
  OutlinePen.m_PenColor.SetColorValue(COLOR_BLUE);
  OutlinePen.m_PenStyle = n_ACSIL::s_GraphicsPen::e_PenStyle::PEN_STYLE_SOLID;
  OutlinePen.m_Width = 5;

  sc.Graphics.SetPen(OutlinePen);

  int left = sc.StudyRegionLeftCoordinate + 300;
  int top = sc.StudyRegionTopCoordinate + 300;
  int right = sc.StudyRegionLeftCoordinate + 500;
  int bottom = sc.StudyRegionTopCoordinate + 500;

  sc.Graphics.MoveTo(left, top);
  sc.Graphics.LineTo(right, top);
  sc.Graphics.LineTo(right, bottom);
  sc.Graphics.LineTo(left, bottom);
  sc.Graphics.LineTo(left, top);
