[GAMEPLAY] COLOR BOXES OVERSHADOWING CURSOR

Regardless of the game mode every time an enemy gets near, anything I hover over gets a giant ugly box over it. Which sometimes makes it difficult to cast spells.

It only happens while enemy champions are near by, it even highlights the turret, making a giant colored shadow box over the entire turret (taking up a good portion of the screen.

Also, I guess on another side note, I have uninstalled and wiped LoL temp files and reinstalled 3 times.

Any help would be appreciated.

P.S. I looked for a common topic for a plausible fix, but I couldn't find one, if there is a quick fix, feel free to let me know.
