title: QPushButton Stylesheet Causes Artefact On Press
body: <p>I'm having a problem with my stylesheet on a QPushButton:</p>
  
  <pre><code>QPushButton#convertButton
  {
      color: #00FF00;
  }
  </code></pre>
  
  <p>Pretty simple as you can see and the text colour gets set correctly. The problem arises when i click the button, a strange artefact appears like an inner part of the button has been selected. Unfortunately i don't have enough rep to post an image.</p>
  
  <p>If i remove the stylesheet the artefact does not appear on press. </p>
  
  <p>Any help welcome. Thanks!</p>
