Rammus Visual Bugs

I noticed that when I played Rammus that a long purplish/pinkish line was reaching to the edge of the bottom left screen as I was doing my first clear. It happened throughout the matches I've played him. It's pretty inconsistent, and it's not game breaking. Just thought I'd bring it up. All my settings are on Very High, 60fps, using the full metal skin. I'm not sure if it's a skin specific problem or not.
