For the strangest reason, whenever I'm in Survival Mode, have the Entity Inspect option turned on, and have an entity leashed, my screen either does REALLY dark, turns completely blue, or the experience bar at the bottom completely vanishes. This issue began here however it was discovered that it was this mod that is causing these strange issue.

OS: Windows 10 Home Edison 64-Bit
Graphics Card: Intel HD Graphics 4400
OpenGL Version and Build: 4.3.0 - 20.19.15.4531
RAM: 8GB

I tried to recreate this on my end. Thus far without any success. Can you give me your mod list?

Huh, I did just finish building my new PC with a GeForce GTX 1060, and that bug seemed to have gone away entirely. Guessing it was my old PC's integrated GPU
