(1.10) Tested informally with a single shulker box in my inventory that had 26 occupied slots and one open slot. Placing it on the ground so that I have no shulker in my inventory was fine. As soon as I put the box in my inventory the lag kicked in when opening my inventory.

With or without a shulker in my inventory, opening a chest was lag-free.

I don't see this behavior with an Ender Chest. Ender Chest(s) seems to have no effect on Inventory lag.

Edit: Michael Brearley, renaming the Shulker Box does not seem to have an appreciable effect on the lag.

Edit2: I noticed Michael has a texture pack enabled. I disabled the official beta Texture Update Pack and re-tested. Observed same behavior. It might have been slightly improved in general but there is a clear difference between opening the inventory without a shulker box and opening the inventory with a shulker box.

Ran into this this evening. Very aggravating. Win10, 1.7.1

I tried putting a single bucket of lava over the top of the drop (it's currently a 4x2 column) across some fence gates and will see if that helps force the guardians down.
