CCTextureAtlas.cpp error qgl2DrvAPI_glClear:56 Error: Unknown: 0x506

在AppDelegate 里面写了如下的一个CCScene,在Layer里面设置了CCGrid3D,代码如下:
CCLayer* ccLayer = CCLayer::create();
CCGrid3D* ccGrid = CCGrid3D::create(CCSizeMake(32, 32));
ccGrid~~>setActive;
ccLayer~~>setGrid(ccGrid);
CCScene* ccScene = CCScene::create();
ccScene~~>addChild;
pDirector~~>runWithScene(ccScene);

然后写了一个WallpaperService,但是在设置壁纸的时候会报下面的错误
08-28 12:22:09.782: D/cocos2d-x debug info(12481): OpenGL error 0x0506 in jni/cocos2dx/textures/CCTextureAtlas.cpp drawNumberOfQuads 686
08-28 12:22:09.802: W/Adreno200-ES20(12481): <qgl2DrvAPI_glClear:56>: Error: Unknown: 0x506

如果不设置CCGrid3D的话,壁纸是可以运行正常的, 2.1.4 和 2.1.5都会出现这个问题,求大神帮忙

Hey, Have you got any suggestions for me? I also have a similar problem with a wallpaper implementation. Take a look … http://cocos2d-x.org/forums/6/topics/30639?r=38743#message-38743
