Strange Textures on Vi [GAMEPLAY]

Hi their League of Legends forums! I was playing my first PvP game as Vi and I was changing up the graphics settings from very high to high and i noticed that Vi's textures had been broken I got a bluish image on her body and i was wondering why this happened I changed the graphics setting back and forth to no avail. I noticed doing some moves she would quickly flash back to her normal skin, she was still fully playable but it was just strange, I wanted to report it.

Also I am running League of Legends on a Mac
