The screen will flicker when I scale and rotate a CCSprite.
I’m using cocos2d-1.0.1-x-0.13.0 beta.
I uploaded the code and project at GitHub: https://github.com/diwu/Screen-Flicker-Bug-Cocos2d-X
Also there’s a video at YouTube demonstrating the bug: http://youtu.be/EQCiwenAIvs
Note: this bug only appears in iPhone 4s. The code works well on iPhone 4 and Nexus S.
