title: xlwings Screen still Updates When screen_updating Off
body: <p>I have 10-12 xlwings fairly complicated xlwings live writes I'd like to do.  If possible, I'd like to have them appear simultaneously.  I've also read that turning <a href="https://docs.xlwings.org/en/stable/api.html" rel="nofollow noreferrer">screen_updating off might speed up the writes</a> which would be nice.</p>
  
  <p>However, I must be making a mistake on implementation as the below sample code you can see the writes happen one at a time if you watch closely.  For my bigger DataFrame writes this is more noticeable.</p>
  
  <pre><code>book = apps.active.books[_FILE]
  sheet = book.sheets['Sheet1']
  
  book.app.screen_updating = False
  for i in range(100):
      sheet.range(f'A{i+2}').value = 'VALUE'
  
  book.app.screen_updating = True
  </code></pre>
