title: What causes texture corruption in libgdx when minimising a game, going to the home screen and then going back into the game?
body: <p><a href="https://i.stack.imgur.com/haLMq.png" rel="nofollow noreferrer">Tablet screenshot</a></p>
  
  <p>When I start and run my libgdx game in Android, everything is fine.  If I navigate back to the home screen and then go back into the game, I get this texture corruption.  </p>
  
  <p>The corrupt objects are either Label or TextButton. The ImageButton objects are fine. The problem never happens when running inside the emulator in Android Studio. It only ever happens when deployed onto a physical phone or tablet.</p>
  
  <p>Does anyone recognise what this issue might be?  Thanks.</p>
