Form Shrinking Once upon KeyDown

Question

My Program resizes once smaller with smaller pictureboxes and buttons when I receive a keypress, I reproduced the behavior here, any ideas? Visual Studio 2019

Here is the bug problem https://drive.google.com/file/d/1e2h4UhgOosk6u7sl21T7EVSqDpCDXqaH/view?usp=sharing it on my PC it shrinks about 20% once on keypress

EDIT: The behaviour stopped by rebooting after setting the display scaling to 100% for both monitors in Start>Display Settings>Scale and layout. I needed to reboot after then rebuild project. But the problem is still there when I scale the display again.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Windows.Media;

namespace tesatbug
{
public partial class Form1 : Form
{
MediaPlayer audio1;

    protected override bool ProcessCmdKey(ref System.Windows.Forms.Message msg, Keys keyData)
    {
      // audio1 = new System.Windows.Media.MediaPlayer(); //uncomment to reproduce form shrink
        MessageBox.Show("cheese");  return true;

    }
        public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {

    }
}

}

If you need to change the size of the form, you can modify its width and height properties and use a loop to make it an animation.

            for (int i = 0; i < 20; i++)  
            {  
                this.Height -= 7;  
                this.Width -= 10;  
                Thread.Sl*eep(10);  
            }  

You can also consider using WPF, which has rich animation effects.

<Grid>  
        <Button Content="Click" Width="100" Height="30">  
            <Button.Triggers>  
                <EventTrigger  RoutedEvent="Button.Click">  
                    <EventTrigger.Actions>  
                        <BeginStoryboard >  
                            <Storyboard  RepeatBehavior="Forever" AutoReverse="False">  
                                <DoubleAnimation  Storyboard.TargetName="myWindow"  
                                      Storyboard.TargetProperty = "(Window.Height)"  
                                        To="300" Duration="0:0:5"/>  
                                <Storyboard  RepeatBehavior="Forever" AutoReverse="False">  
  
                                    <DoubleAnimation  Storyboard.TargetName="myWindow"  
                                      Storyboard.TargetProperty = "(Window.Width)"  
                                        To="300" Duration="0:0:5"/>  
                                </Storyboard>  
                            </Storyboard>  
                        </BeginStoryboard>  
  
                    </EventTrigger.Actions>  
                </EventTrigger>  
            </Button.Triggers>  
        </Button>  
    </Grid>
