[GAMEPLAY] Texture artifacting bug

I experienced this bug in a bug earlier today, when most of the textures in the UI were artifacting. Health bars, item icons, the tab menu, and spell icons were all skewed and hard to see.

The bug occured on my mac air, right after i changed my scroll type in my settings from natural while in game (On the trackpad section in the settings application). Switching the scroll type back caused no change, and the bug persisted until the end of the game, but stopped after that game.
