in the latest snapshot of 16w39c this bug has affected my chests, shulker boxes, signs, item frames and armour on armour stands. sometimes when i am moving about the place these items flash slightly and a become transparent (i can see through them).
Environment
Put your operating system (Windows 8) and Java version if you know it here
This is caused by the elytra you have on one of the stands. Therefore this issue is a duplicate of, or is related to MC-99353.
