http://cocos2d-x.org/boards/6/topics/20141?r=20567#message-20567

for iOS:
in AppController replace the gl-view creation with:

    EAGLView *__glView = [EAGLView viewWithFrame: [window bounds]
                                     pixelFormat: kEAGLColorFormatRGBA8
                                     depthFormat: GL_DEPTH24_STENCIL8_OES
                              preserveBackbuffer: NO
                                      sharegroup: nil
                                   multiSampling: NO
                                 numberOfSamples: 0];

for Android:
in game activity:

    public Cocos2dxGLSurfaceView onCreateView() {
        Cocos2dxGLSurfaceView glSurfaceView = new Cocos2dxGLSurfaceView(this);
        glSurfaceView.setEGLConfigChooser(5, 6, 5, 0, 16, 8);
        return glSurfaceView;
    }
