Seems to be up to cloud height. Wasn't there when i opened the world. Not sure what would have caused it. It shown up while wandering around, not changing settings or using commands apart from /gamemode
EDIT:
Seems to vary with the time of day and/or the way the player is facing

You said in the other bug report to update my drivers. That fixed this issue here 🙂
But it didn't fix the other issue (i will comment on that with some more info)
