When I hover my cursor over a minion, champion, turret, or even some monsters, often a red or blue square appears covering whatever object I was targeting. This is a new phenomenon for me that just started occurring with the last patch on the new SR.
The way i fixed it was going into NVIDIA Control Panel and setting Anisotropic filtering and every Antialiasing to OFF. After that i gone back to game and the squares dissapear. Surpsrisingly after that i've clicked the Restore button to check wich of those options actually fixed the squares bug and when i gone ingame, the squares weren't there, even with all NVIDIA settings Restored to default (Note that after hitting Restore button the options gone back to ON and Application Controled, so i am not exactly sure how the bug fixed by doing all that... good luck to all)
yea same, how do we fix it?
It's happening on more than just the SR map, it's happening to me on Twisted Treeline, Howling Abyss and Crystal Scar. Re-installing/repairing won't fix it, someone's put something out in one of these about this with a fix to some config file but it doesn't work for everyone.
Riot still hasn't acknowledge it yet.

bumping for support
