title: Chromedriver maximize issue
body: <p>I'm new to this forum as well as to programming and selenium.
  I'm trying to maximize my chrome browser using selenium python(using the below code) and everytime selenium opens the browser it would not maximize the whole window.It maximizes only half the screen with "data:," already filled on the address bar.</p>
  
  <pre><code>self.driver = webdriver.Chrome() 
  self.driver.maximize_window()
  </code></pre>
  
  <p>I also tried </p>
  
  <pre><code>options=webdriver.ChromeOptions()
  options.add_argument("--start-maximized")
  driver=webdriver.Chrome(chrome_options=options)
  </code></pre>
  
  <p>but doesn't help</p>
