title: Removing and Adding TextGeometry freezes the scene
body: <p>I am trying to create a clock with the help of Text Geometry. In order to update the time I need to update the text in  Text Geometry which can be done by removing and recreating a new Text Geometry. </p>
  
  <p>Every time I add a new Text Geometry it freezes my browser:  </p>
  
  <pre><code> // Remove old mesh
    earthClockMesh.geometry.dispose();
    earthClockMesh.material.dispose();
    group.remove(earthClockMesh);
  
  
     //add new mesh
    earthClockMesh = this.getTextMesh(
      new Date(diluatedTime).toLocaleString(),
      textMaterial
    );
    group.add(earthClockMesh);
  </code></pre>
  
  <p>Anybody know better way way we can update the text in Text Geometry without freezing browser.</p>
