Hello, For the past week I have been playing Minecraft on 1.8 and 1.8.1 as usual. However, my screen suddenly half-loads and a large number of blocks do not show up on the screen. I have tried relogging, reloading chunks with f3 + a, and restarting my Minecraft client. I do hope this is not my laptop's problem as its not going to be my processor having the problem. It's an HP Envy dv7 laptop with dual core i7-3670k, 8gb RAM, and Intel HD Graphics 4000.
