I've been having a weird issue with a G502 mouse since the housing update. Very rarely, and somewhat sporadically, my mouse will jump sensitivity for a brief second and the in-game camera goes out out of control. This mostly happens when looting or in the housing editor. I don't have any issues with any other games, in windows... just with ESO, and only since the Housing update.
Since you've had odd G502 issues have you experienced anything like that?
