[GAMEPLAY] Graphical Bug on Cursor Hover

When I hover over an ally minion/turret/champion or enemy minion/turret/champion, i have a graphical box pop up that covers the area of that model. So if it's a friendly tower, the entire tower becomes covered by a giant blue box. When I die and come back, it stops for a bit, but it always begins happening again. I'm not sure of the amount of time that it takes to reoccur, but it always does. Thanks for any help that can be provided.
