title: Black Screen appears while maximizing winform which has ElementHost as child
body: <p>I added ElementHost as child to winform. While maximizing window, black screen appears before showing form.</p>
  
  <pre><code>public Form1()
  {
      InitializeComponent();
      System.Windows.Forms.Integration.ElementHost host = new 
      System.Windows.Forms.Integration.ElementHost();
      host.Dock = DockStyle.Fill;
      Controls.Add(host);
  }
  </code></pre>
  
  <p>Maximizing window behaviour works fine without element host as child. Provide possible solution to avoid black screen on maximizing winform having element host as child .</p>
