Describe the bug
The entity flickering randomly depending on how you look at it, such as moving your mouse around the entity, moving around the entity, looking at different angles, etc.

To Reproduce
Steps to reproduce the behavior:

1. Place down an entity, preferability one that doesn't move such as an armor stand.
2. Walk around it while looking at it while moving your mouse.
3. At certain points the entity will disappear for a split second & reappear, aka flicker.

Please use the issue template and provide the requested information.

Edited the OP

Configs for EntityCulling & RenderLib are their defaults, did another test after deleting the contains of my config folder just to have them regen with their defaults.

Yes, it just depends on the angle you're looking at for the mobs to disappear for a split second.

It seems to happen if there are more than 4-5 mobs.

Oh... and the modlist when I took the above GIF.

RenderLib-1.12.2-1.1.1
EntityCulling-1.12.2-6.0.2
HadEnoughItems_1.12.2-4.22.0
_MixinBootstrap-1.1.0

Not reproduceable for me.

Did you change anything in the EntityCulling or RenderLib config?
Are you able to reproduce this in a flatworld with only 1 entity loaded?

This looks like some ID shifting when a mob enters/leaves the FoV.

Are you able to reproduce this with EntityCulling-1.12.2-6.1.0?

Was able to reproduce with EntityCulling-1.12.2-6.1.0.
