I've been experiencing this ever since I upgraded to the 1.5 pre-release, I was fine in 1.4.7. I don't find it that annoying (although caves look like they are full of fireflies), but I hope they fix it in a small update after 1.5 if they can. I know red3yz has this exact same problem, but he is able to play fine, and I am too. Hope this helps!
