You can't turn clouds off without it breaking (It's hard to explain, video attached)

When going to turn the clouds off it would just keep the clouds in my vision. 
It went away with relaunching but I tested it again and this still happened, reloging loads the world with the same effect.

Not sure if this is a client side bug or if its a bug with the snapshot but friends told me I should report it just in case.

Images and video of whats happening linked
I hope this helps.
