title: Button not responding after a few clicks lib-gdx
body: <p>I cant seem to find an answer to this. Why does my start button freeze after a certain amount of clicks(3)? It works for the first 3 clicks and then decides to stop working. I can still see that the screen is responding(the button becomes red when clicked), but the text on it doesn't change. It's like the click listener stopped responding.</p>
  
  <pre><code>public class MainMenu implements Screen{
  
      private Game game;

      private TextButton Internet_btn;
  
      private TextButton Settings_btn;

                  Gdx.graphics.getHeight())); //create a new stage with viewport to draw 2d stuff on
