I had to exit the game and come back for it to reset.
2x i7-3960x extreme 3.3ghz 6-core on dual cpu motherboard (overclocked: 5.0ghz, 4.9ghz)
3tb hdd & 240gb ssd (game is on hdd)
3x 7970 msi twinfrozr 3gd5 crossfired (overclocked: .993v 1050mhz 1500mhz, .993v 1250mhz 1500mhz, .993v 1150mhz 1450mhz)
windows 7 ultimate 64bit
I have the latest drivers for all of my components and latest w7 version.
I also have FPS limited at max game settings.
Was wondering if this is a common problem, or if this was a one time thing. also, when in the shop and I'm clicking excessively (OCD) very rarely I would get screen flashes so quick that I can't tell the color (yellow or white).
Thanks Riot, you're the best!
Edit: also, my system is stable as I have done numerous stress testing and stability testing with the above mentioned clock speeds. every game works fine (except for known issues)
