Ever since I updated to 1.8 and above, these white lines have been forming around blocks, Its very annoying and I cannot play minecraft like this, I have checked with my nvidia driver, I have been able to get the same results on other computers. The white and black/transparent lines do not effect performance but are annoying. Its hard to see them in the picture but I have a 25 inch screen, so i see them pretty clear. I cannot get the same result with my intergrated Intel Graphics card. So I believe its to do with minecraft and my GPU. I always use my Nvidia 610m for gaming and my intergrated graphics for older games. Please help. I have to play on older versions now Thank you
