Starting Chest is Invisible

I just started a world to test out all the new features so i started in creative and i put on starting chest. just to look if those changed too. and yes, it was invisible?! i looked at the torches but nothing in the middle. i got closer and saw a invisible chest with stuff in it. i instantly though. OK BUG LETS GET YOU OUT OF THIS GAME! But just when i wanted to make a screenshot the chest appeared. so i dont know. but its still a bug in rendering i think
