title: JavaFX - Border radius <-> Background color
body: <p>If I add <code>-fx-border-radius</code> and <code>-fx-border-width</code> CSS to a simple GridPane, in its corner the background will not be "cut down".</p>
  
  <p>The CSS:</p>
  
  <pre><code>.payload {
      -fx-hgap: 20px;
      -fx-padding: 40px;
  
      -fx-background-color: #2969c0;
  
      -fx-border-radius: 50px;
      -fx-border-width: 5px;
      -fx-border-color: black;
      -fx-effect: dropshadow(three-pass-box, rgba(0, 0, 0, 0.8), 10, 0, 0, 0);
  }
  </code></pre>
