I know what the problem is. If you have a weaker computer like a laptop (in my case) and you have render distance set too far, Minecraft's rendering bugs out and you get what you see in the screenshots. Try reloading the world or decreasing render distance by a few chunks.
No permanent solution otherwise, except get a better computer :/
P.S. I had this issue in 1.8 as well, it's not new.
