Minecraft Texture glitch with the render distance

Okay so i have noticed this glitch before the snapshots and i figured someone would have posted but i guess not.. I was playing Minecraft with the latest snapshot and i wanted to turn my render distance up to 15 chunks so i could find myself a nether fortress but the textures where the rendered area would have been glitched out and starting flipping out with random block and textures and a ton of random stuff Haha and it started duplicating other pieces of rendered land !.

*What I expected to happen was that i would have gained render distance and i would have found what i was looking for.

What actually happened was...:
My rendered chunks flipped out in the distance

Steps to Reproduce:
1. set your render distance at 13 chunks
2. max settings for graphics
3. and set your chunks to 15 or higher

i will send some screenshots of what happened

NOTE. i was not using any texture packs and i do not have any mods installed.

The screenshots from the nether are from the latest snapshots and the other screenshots are from a different version before the snapshots

Please try your best to fix this guys! i wish you the very best.
