Horrible redraw performance of the DataGridView on one of my two screens

class CustomDataGridView: DataGridView
{
    public CustomDataGridView()
    {
        DoubleBuffered = true;
    }
}

class CustomDataGridView: DataGridView
{
    public CustomDataGridView()
    {
        DoubleBuffered = true;
    }
}

typeof(DataGridView).InvokeMember(
   "DoubleBuffered",
   BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.SetProperty,
   null,
   myDataGridViewObject,
   new object[] { true });
