Describe the bug
When a mirror is placed, I get a very circular effect and can only look around every 8 seconds but then does the same thing in like 2 seconds if I look at the mirror. The mirror looks black but I have to destroy it to be able to actually play Minecraft because it keeps freezing with this circular oval like thing.

Logs
No logs, doesn't show anything.

To Reproduce

1. Place mirror
2. Look at it. Boom.
