Firstly I wasn't where to put this thread, so I hope it is in the right spot but I really need some help. I was playing minecraft the other day when I started getting a bit of lag, so of course like any player that has seen the forums a few times knows that optifine is one of the best, if not the best fix for lag. So I downloaded and installed optifine. Everything was working fine, but when I switched back to my regular account (optifine didn't seemto help at all so I went back to complete vanilla) I got this insanely weird glitch/error. Its only on the vanilla version, the optifine version doesn't have this problem. But basically, I can see through chunks, the colors get mixed up, and it's just impossible to play on. I have been unable to find any working fixes through google and other searches but if you have the link to something you think may help feel free to post it. Here's a picture of what the glitch looks like. (this happens on both multi and single player.)
