I’m creating a .net app that uses webview2 to view sveltekit static app or any static HTML file, but I got this weird graphical issue as shown in this video: https://imgur.com/W9NdOjT

any suggestion as to how I can remove it?

I tried doublebuffer and didn’t work

this is the main part of my code:

public partial class MainForm : Form
{
    public MainForm()
    {
        InitializeComponent();
        InitializeWebView();
    }

    private async void InitializeWebView()
    {
        await webView.EnsureCoreWebView2Async();

        webView.CoreWebView2.AddHostObjectToScript("myMethods", new MyMethods());
        webView.CoreWebView2.Settings.AreDevToolsEnabled = Program.IsDebug;
        webView.CoreWebView2.Settings.AreDefaultContextMenusEnabled = Program.IsDebug;

        string svelteKitPath = Program.IsDebug ? "http://localhost:3005" : Path.Combine(Application.StartupPath, "wwwroot", "index.html");
        webView.Source = new Uri(svelteKitPath);
    }

    private void InitializeComponent()
    {
        webView = new MyWebView2();
        ((System.ComponentModel.ISupportInitialize)webView).BeginInit();
        SuspendLayout();
        // 
        // webView
        // 
        webView.Dock = DockStyle.Fill;
        webView.Name = "webView";
        // 
        // MainForm
        // 
        ClientSize = new Size(800, 450);
        Controls.Add(webView);
        this.DoubleBuffered = true;
        this.Name = "MainForm";
        this.Text = "MainForm";
        ((System.ComponentModel.ISupportInitialize)(webView)).EndInit();
        this.ResumeLayout(false);
    }

    private class MyWebView2 : Microsoft.Web.WebView2.WinForms.WebView2
    {
        public MyWebView2() : base()
        {
            this.DoubleBuffered = true;
        }
    }
}
