So recently after Minecraft has updated to 1.4, I've been having problems with the game displaying graphics. Anytime a play for a good 2 minutes, the textures go all crazy. I've been using the cape mod and optifine with these problems occurring though i have also checked to see if i have this problem with no mods and I still do. No matter what texture pack i use, HD or normal, i get the same problem even with the default texture. Any help is appreciated!
