Why when using contextmenustrip right click for the first second the menu is not in mouse position?

In the constructor:

ListViewCostumControl.lvnf.ContextMenuStrip = contextMenuStrip1;
ToolStripMenuItem item1 = new ToolStripMenuItem();
item1.Name = "Open File Folder Location";
item1.Text = "Open File Folder Location";
item1.Click += contextMenuStrip1_ItemClick;
ToolStripMenuItem item2 = new ToolStripMenuItem();
item2.Name = "Launch File";
item2.Text = "Launch File";
item2.Click += contextMenuStrip2_ItemClick;
ToolStripMenuItem item3 = new ToolStripMenuItem();
item3.Name = "Copy File";
item3.Text = "Copy File";
item3.Click += contextMenuStrip3_ItemClick;
contextMenuStrip1.Items.Add(item1);
contextMenuStrip1.Items.Add(item2);
contextMenuStrip1.Items.Add(item3);

Then i check that the listView is not empty only then show the menu:

private void contextMenuStrip1_Opening(object sender, CancelEventArgs e)
        {
            if (ListViewCostumControl.lvnf.Items.Count == 0)
            {
                e.Cancel = true;
            }
        }

And the event when i make right click to show the menu:

private void Lvnf_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Right && ListViewCostumControl.lvnf.Items.Count > 0)
            {
                var hitTestInfo = ListViewCostumControl.lvnf.HitTest(e.X, e.Y);
                if (hitTestInfo.Item != null)
                {
                    var loc = e.Location;
                    loc.Offset(ListViewCostumControl.lvnf.Location);

                    var items = ListViewCostumControl.lvnf.CheckedItems;
                    if (items.Count > 0)
                    {
                        contextMenuStrip1.Items[2].Enabled = true;
                    }
                    else
                    {
                        contextMenuStrip1.Items[2].Enabled = false;
                    }
                    contextMenuStrip1.Show(this, loc);
                }
            }
        }

When i make mouse right click for a second or less the menu of the contextmenustrip is show on the top of the form1 then it's showing on the listView where the mouse is on the select item.

But how can i make that it will show the menu only on the item ?

I dragged the contextMenuStrip1 in the designer from the toolbox and i see now that the contextmenustrip is also show as menu in the top left of the form1.

This is a screenshot showing the menu right after i make right click on the top left of the form:

First

And this is second later the menu is moving to where it should be on the first time:

First1

The problem was this line:

contextMenuStrip1.Show(this, loc);

this prefer to form1 control and it should be the listView control instead:

contextMenuStrip1.Show(ListViewCostumControl.lvnf, loc);
