Moving mouse (Not holding left or right click) also moves camera when pressing any movement key. Character spins uncontrollably, never had this issue before until this restart. Did try yall try and sneak test something?
Edit: Anyone else having same issues? Or any resolution
Edit 2: Found a fix apparently the reset may have changed some peoples hidden settings… Try out ---- /console rawMouseEnable 0 ---- That should fix it.
This isn’t happening to me. My camera still only rotates if I hold in a mouse button.
This is happening to me as well.
Oh wow hmm atm its a temporary fix atl. Couldn’t play the game at all with the mouse movement
I just want them to fix the option they randomly keep enabling what blocks trades. Happens now and then someone will try to trade me something and I’ll “auto” decline. Nope. Blizz has once again ticked the “decline trades” in my options for me. WTF?
This is happening to me as well.
A friend of mine was also having this issue today.
Glad to see this post, I thought my mouse was getting ready to die on me.
Try this 
Same thing happened to me, too. I used the fix in the first post, which corrected the look issue, but the mouse still feels “off”. I can’t quite explain it. Sluggish maybe?
yea, had the same issue. the /console command fixed it
