[Mac] Game is detecting phantom inputs.

I don't have a good way of explaining this in detail so i'm going to just link the video I took. Persists between restarts of game, Steam, and computer. Unplugged mouse, continues to happen. In general I don't think it's an input issue on my end as it can be seen happening in the background right after the "Heroes" tab is clicked.
