You said to turn off the VBOs setting. I saw that it was already off, so I turned on VBOs and VSync. It didn't crash when opening the world this time.
It happened to me too, rendering distance 12 chunks, also note that it isn't obsidian, it's item/block resource picture. My report (if helps): MC-85005
