title: Where is this warning being raised 'QApplication: invalid style override passed, ignoring it.'?
body: <p>My code is throwing the warning (not sure if this is actually a warning)</p>
  
  <pre><code>QApplication: invalid style override passed, ignoring it.
  </code></pre>
  
  <p>but nothing else. It does not tell me which part of the code is raising it.</p>
  
  <p>How can I know which part of my code is triggering this warning?</p>
