Turning camera with mouse works intermittently

I have googled so many different solutions, and NONE of them are it.

PROBLEM: The game will randomly decide it won’t register 90% of the camera turning with mouse. Usually, this also messes with running forward by holding down both left and right buttons.

It is not the mouse. My mouse works fine everywhere else.

It is not an addon randomly tossing a frame on top of everything. It still works; it just works VERY VERY BADLY. Even so, I have tried playing without any addons.

Looting at cursor, console commands for mouse, vsync, and other random settings have all been supposed solutions from googling. NONE OF THEM WORK, and I suspect people think it worked for them because this is an INTERMITTENT problem. It does not happen immediately when logging in.

Has anyone else actually fixed this LONG TERM? How? It is a truly awful gameplay experience.

I know this is an old post and you have by now figured it out, but I just had the same issue. If someone else stumbles upon this thread my issue ended up being that I had an empty bartender actionbar in the middle of my screen. Took me longer than I’d like to admit to figure that out…
