title: OrthogonalTiledMapRenderer and normal Spritebatch renders a white box?
body: <p>I am using Libgdx to render a TileMap as a background of my game. I might render some different layers later on.
  Without the tilemap render and a single background picture it works correctly!
  Something strange happens when i use the TiledRender just take a look at it:
  <img src="https://i.stack.imgur.com/Zcfe9.jpg" alt="tiled scene with big white box in the upper left"></p>
  
  <p>The two white areas are normally a touchpad and a character.</p>
  
  <p>The touchpad and the character are rendered with:</p>
  
  <pre><code>@Override
     public void draw(SpriteBatch batch, float parentAlpha) {
        sprite.draw(batch);
     }
  </code></pre>
  
  <p>My Map where i render my TileMap looks like this:</p>
  
  <pre><code>public class Map extends Actor {
     private TiledMap map;
     private OrthogonalTiledMapRenderer render;
     public int[][] mapArray = new int[Config.X_SIZE][Config.Y_SIZE];
  
     public Map(TiledMap map){
        this.map  = map;
        this.render = new OrthogonalTiledMapRenderer(map,(((float)Config.VIRTUAL_VIEW_HEIGHT/Config.Y_SIZE)/(float)Config.TILE_SIZE));
        this.toBack();
     }
  
     @Override
     public void draw(SpriteBatch batch, float parentAlpha) {
        this.render.setView((OrthographicCamera) this.getStage().getCamera());
        render.render();
     }
  }
  </code></pre>
  
  <p>any sugestions to fix the SpriteBatch problems?</p>
