Chest crafting shadow glitch

When crafting chests it will display an unusually shadow change on the blocks in inventory. It only happens when crafting chests i found.

As you can see the shadow appears on the right at first, then once the chest recipe is put in the shadow changes to the left side of all the blocks in the inventory.

NOTE: I also found out later that just picking up a chest and moving it around in the inventory, chests, crafting tables, etc causes the light glitch as well.
