so while watching a yt video just now my cursor went crazy by teleporting to the opposite corners of the video player and clicking before teleporting to the "back" button on my browser and shortly thereafter closing it, while i have ridiculously high mouse sensitivity as a choice,a "back" button on my mouse, and had a drawing tablet connected with my phone on top of it, considering how simultaneously quickly and long it happened, i fear that it might not just be a hardware issue. any guesses as to what the actual fuck happened?
