Ok so this happened over the last update. Everything else on my computer is fin but when I go to play league I cant see the top of my screen (so the kills/timers) or my mana bar or the right side of the map etc, i tried every resolution and nothing works and tried to edit the res in the config files but nothing worked. Please help, it's extremely annoying to play with a bunch of my screen missing. Ok for some reason my map is fine now but the top and left side is still messed up.
