IPHONE 4S : when I scale up a layer, some sprite child are broken +screen shot

Hello guys :slight_smile:
I w8 for spring coming. haha

I made 2 layers(CCLayer) , first one is game layer, second one is interface layer.
CCTMXTiledMap exists in game layer.
so, when I scale up this layer is enable to scroll it by setPosition , sprite child’s pixels are broken.
these sprite are reordered by y position once.
in this case, label blinks in interface layer.

this problem occurs on device(IPHONE 4S!), not simulator
