When I load any world on the new 1.8 update, the entire world and items are invisible and some blocks are black. I can walk around, break blocks (invisible and black), kill mobs, interact with blocks, and place blocks like normal; but it will not fully render. I tried setting the java preferences higher and increased the RAM to 4MB but still no change. All Minecraft video settings are set for best performance as well. In the screenshots I attached, I loaded a super flat world because it has less blocks to render but still have the same problem. Can anyone help? Thank you
