As I was exploring the world, I came up on a giant mountain. After I climbed to the top of the summit I slept in a bed. I then woke up and decided to start climbing down the mountain. On my way down there was a cliff that was very steep and goes down very far. Since my computer is slow, I had to put the render chunks option to 2 chunks or in earlier versions tiny. I wanted to see if there was any water that I can dive into so I went to the menu and turned the render chunks to 20(I didn't not which option I should do so I chose this one) and when I did then what you see in the picture happened. Whenever I moved the camera, the glitchy landscape would change. I decided to look for another way and I turned the render chunks back to 2. When I came to a ledge too tall for Steve, I broke the dirt block so I can climb up the ledge. The dirt was destroyed but the snow was still there. It was floating and you can even stand on it. I did it on another platform and the same thing happened. I'm not really sure if it was this glitch that caused it or a separate glitch. Next I came up to a cow and wanted to kill it for it's meat. When I hit it though it didn't hurt it. I did it a couple more times. I kept coming closer since I wanted to killed it but found out that the cow wasn't even solid. I started experimenting with it and see if I could place anything where it is. What's interesting is that I can't place anything where the cow is. Then I noticed a floating bunny that was just standing there on nothing. I went down even further and I fell about 3 or 4 blocks. I heard a thumping noise when I landed on the ground as if I have taken damage. I didn't take any damage though. When I when to the base of the mountain I was teleported back. When I was teleported back I was a little bit off the ground and I had to start jumping to get back on the floor. When I was in the air I couldn't move and the camera would start shaking and I wouldn't move. I decided to try to climb down the mountain again, seeing the same cow and bunny and having no fall damage. The same thing happened. Since I couldn't take any fall damage I decided to jump off the cliff. While I was falling I took a heart of damage and since the cliff was so high, you would normally get insta-killed by the fall but when I landed on the ground, I didn't take any damage when I landed, but after walking a few steps I died and lost all my items. I quit the game and went to look for a place to report the bug. That leads us here. I'm not really sure what caused this glitch. It could be my computer or Java, but it could be because I recently played a snapshot. I forgot which snapshot it was but when you move the objects kind of get blurry. I did this snapshot in a separate world I made just for snapshots though. If you can help me find the cause of this glitch I will be very pleased. Thanks.
