Windows Show Desktop causes WinForms elements to stop updating

Is there a simple way to have elements on a form keep updating even after I click on Windows Show Desktop? The following code updates the value in textBox1 until I click on Windows Show Desktop (Windows 10 - click on the bottom right of the screen). I prefer not to use Application.DoEvents().

void Button1Click(object sender, EventArgs e)
{
    int n = 0;
    while(true) {
        textBox1.Text = n++.ToString();
        textBox1.Refresh();
        Update();
        // Application.DoEvents();
        Thread.Sleep(200);
    }
}

Using Thread.Sleep blocks the current thread (UI thread); you can fix it like this:

private async void button1_Click(object sender, EventArgs e)
{
    int n = 0;
    while (true)
    {
        textBox1.Text = n++.ToString();
        await Task.Delay(200);
    }
}
