Glitchy or Static ring around the turrets

When you guys start playing you should look at the turrets base and move around. Their seems to be a Static ring or squares at the base whenever you move past or around them. I first saw this while playing Co-op vs. A.I. as for my first time. It may not bother other people or they may not see it because it is too small to see and they are probably not even paying attention to the small things. I love the visuals and the new monsters. Its just the little things the bug me a bit. So I thought I point this out. If there are other things out of place in the new Summoner's Rift map I'll let you guys know.

P.S. I don't have proof of evidence but you just have to see for yourself is all.
