I'm having the same problem, too. I do not have an NVIDIA driver, so it can't be that for me. I am only running into this issue when I use Renthal311's texture packs, but I use quite a few (Nobel's HD 2k, Optimized Vanilla, Hybrids HD Plants and Herbs, HD Ivy...and a lot more, but the problem is only occuring in the "plants" and "farmhouse" folder of the texture file). I hope the fix from Bauldric works for me. I've contacted the mod author, also, so if it doesn't work maybe Renthal knows what's going on.
