All textures and skins turn neon pink after a while of playing on servers

Basically, when playing on the hive and other servers for a long period of time, (About 1-2 hours) people's skins, and other textures turn solid pink, i thought at first it was the missing texture glitch with the pink and black squares, but nah, it didn't help at all. And it only stops for another 1-2 hours if i fully close the game. Its actually annoying as ever and i know a few other people who have this issue.
