League graphics gone wrong (Seizure Warning)

I cannot stress enough that there is a Seizure Warning on this video as it consists of almost constant flashing lights. This was a game I played earlier with some friends. I started it by relogging, and when that didn't fix the problem I just hit record and played the game out. After restarting my computer it was fine. This had never happened to me in a game before, and after editting down the 19:30 minute long video, my eyes still hurt.
