Hologram based resource packs like holoprint and structura causing major lag

Issue: Starting with the .82 hotfix, holoprint, which is a resource pack that is created by a website where you upload a structure file to, and it gives you a hologram like version of the structure block in your world, tied to an armorstand to help you build it in your survival world, now drops frames down to under 5fps, when it used to cause little to no performance hit pre-patch. The lag is greater the more blocks used for the structure, and small enough structures may produce no lag. I do not have any sense of scale for what causes no lag, and where the break point is for lag to start

Reproduce: Using a structure block, save the structure of a larger sized build, one that uses at least 3 dozen total stacks of blocks. Upload that file to https://holoprint-mc.github.io/ and follow the instructions to create the resource pack. Once created, install the pack, apply to global resources or the world directly, and place down an armorstand to display the hologram. You will experience lag.

Work Arounds: It has been found that if you place an item in the armorstands hand, and use the control to show 1 layer at a time, the lag will mostly go away, but drops in FPS for a few seconds when changing layers.

Expectation: Prior to the .82 patch there was no noticable FPS drop on my PC from using a single holoprint, regardless of it’s size. FPS drop only occurred with multiple armorstands displaying holograms all at once.

I have attached a holoprint for dev use.
