title: tKinter fullscreen moves window on my secondary display 5 pixels
body: <p>Just implemented a fullscreen option on my tKinter python app.
  Works fine bust some unexpected behaviour.</p>
  <p>My laptop is connected to a secondary screen.
  When switching my app to fullscreen mode, the window on my secondary display moves 5 pixels. When I escape fullscreen mode, the window in my secondary screen moves back to the original position.</p>
  <p>Anyone else experienced this behaviour?</p>
  <p>Thank you for responding. I use a function:</p>
  <pre><code>def switch_FullScreen(*args):
      root.attributes(&quot;-fullscreen&quot;, 1)
      return true
  </code></pre>
