Why Datagridview Scrolling is slow

Question

I am trying to create a project on VB.net. I have a checkbox column attached to the datagridview and one of the data that I have added to the Datagridview has an image column.
I want to hide this image column and show the images in the picture box.
The matter has been successfully completed. The problem is - when scrolling down the keyboard or mouse over Datagridview data, scrolling is slow.
If I don't hide the image column, it doesn't cause any problem.
I would have benefited if an expert had wasted his precious time and collaborated on the solution. Thanks in advance

Sub display_data()

        Dim cmd As New SqlCommand("select * from tbl_pro", con)
        cmd.Parameters.Add("@d1", SqlDbType.NVarChar).Value = Cmb_cmp.Text
        Dim da As New SqlDataAdapter(cmd)
        Dim dt As New DataTable
        dt.Clear()
        da.Fill(dt)
        DataGridView1.DataSource = dt

        DataGridView1.RowTemplate.Height = 20
        DataGridView1.Columns(1).Visible = False
        DataGridView1.Columns(3).Visible = False
        DataGridView1.Columns(4).Visible = False
        DataGridView1.Columns("Picture").Visible = False
        DataGridView1.Columns(0).ReadOnly = True
        DataGridView1.Columns(2).ReadOnly = True
        DataGridView1.Columns(5).ReadOnly = True
        DataGridView1.Columns(6).ReadOnly = True
        DataGridView1.Columns(8).ReadOnly = True
        DataGridView1.Columns(9).ReadOnly = True
        DataGridView1.Columns(10).ReadOnly = True
        DataGridView1.Columns(11).ReadOnly = True
        DataGridView1.Columns(12).ReadOnly = True


End Sub

Hi @jewel ,
You can try setting the DoubleBuffered property of Datagriview.

Imports System.Reflection  

And use DoubleBuffered(dataGridView1, true).
Hope this could be helpful.
Best Regards.
