Bug when returning to windows desktop


I’m a french developer, sorry for my english ^^

I have a problem with my project.
I have created a monogame project for Windows but when I return on the windows desktop with alt + tab the gaming screen turns white and the icon disappears.

I only changed the screen size to 1920 x 1080, fullscreen = true and Windows.title = “The Last Dragon”

Thanks for your help,

public Game1()
    graphics = new GraphicsDeviceManager(this);
    Content.RootDirectory = "Content";
    graphics.PreferredBackBufferWidth = 1920;
    graphics.PreferredBackBufferHeight = 1080;
    graphics.IsFullScreen = true;

protected override void Initialize()
     // TODO: Add your initialization logic here
    this.Window.Title = "The Last Dragon";


Fullscreen Exclusive or Fullscreen Borderless?
