This is quite an annoying bug due to my preferred travel method in my creative worlds being the elytra. It puts the player in some weird state of being in the elytra position while not being able to do anything till they land on a block but in slow motion.

Happens to me on Windows too

I'm getting the same glitch on my realm on Windows.

This is also on my realm. The entire world is covered in these lines for thousands of blocks in each direction. It makes it so when it's night, it feels like day but with a night sky. It's really annoying. I have not seen it in any worlds yet, just my realm.
