Smite Bug
Whenever smite is on CD I get very fine blue flashing lines that connect from smite to my champion, and to the upper left corner of the screen. It doesn't happen all the time, but when it does it's a major irritation and can really cause a headache. I don't have a picture because when I take a screen shot I just get my desktop, (go figure), but it's been a consistent thing since the new rift.
