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;    }
