Solid Pen has problems with transparency when the pen doesn't have transparency. When you work with a FastLine, Line series with a width of pen is thick the left grid line is visible betewen the line although the grid line of left axis are behain.  See the code to reproduce the problem: 
        public Form1()
        {
            InitializeComponent();
          
            tChart1.Aspect.View3D = false;
            tChart1.Legend.Visible = false;
            xxs_FLine1 = new Line(tChart1.Chart);
           // xxs_Gantt = new Gantt(tChart1.Chart);
           // xxs_Gantt.Pointer.InflateMargins = false;
            xxs_FLine1.Color = Color.Yellow;
           
            xxs_FLine1.bBrush.Visible = false;
            xxs_FLine1.LinePen.Width = 6;
            tChart1.Axes.Bottom.Grid.Color = Color.Red;
            tChart1.Axes.Left.Grid.Color = Color.Red;
     
            for (Int32 i = 0; i < 5000; i++)
            {
                xxs_FLine1.Add(i, 10);
         
            }

Missing the setting of an appropriate EndCap, e.g.

    Line xxs_FLine1;
    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      tChart1.Legend.Visible = false;
      xxs_FLine1 = new Line(tChart1.Chart);
      // xxs_Gantt = new Gantt(tChart1.Chart);
      // xxs_Gantt.Pointer.InflateMargins = false;
      xxs_FLine1.Color = Color.Yellow;

      xxs_FLine1.bBrush.Visible = false;
      xxs_FLine1.LinePen.Width = 3;
      tChart1.Axes.Bottom.Grid.Color = Color.Red;
      tChart1.Axes.Left.Grid.Color = Color.Red;

      for (Int32 i = 0; i < 5000; i++)
      {
        xxs_FLine1.Add(i, 10);

      }

      xxs_FLine1.LinePen.EndCap = System.Drawing.Drawing2D.LineCap.Round; //ADD THIS LINE

    }
