title: SpriteKit App glitching on iPhone 4 only
body: <p>So i have recently released an app to the app store and it was working perfectly fine on all devices including the iPhone 4. Then i released an update which changed images completely and also made them better quality. The update was accepted by apple and all was good. I then updated on my iPhone 5 and the update looked fine. I also updated on an iPhone 4s and all looked good. However when i got it on to iPhone 4 two of the images were blacked out. </p>
  
  <p>This is the code that adds one of the images  that is blacked out on the iPhone 4:</p>
  
  <pre><code>    SKSpriteNode* title = [SKSpriteNode spriteNodeWithImageNamed:@"TITLE.png"];
  
      title.position = CGPointMake(self.frame.size.width/2.1, self.frame.size.height * 15/20);
      title.size = CGSizeMake(title.frame.size.width/10.5, title.frame.size.height/10.5);
      [self addChild:title];
  </code></pre>
