I have a few times when the quick wheel menu thinks I am selecting one thing when I actually am trying to get another. For instance I am trying to get to the inventory at 3 on the wheel and the game thinks I picked the character menu at 4. I just chalk it up to imprecise joystick movement on my part and try again. It seems you have to be dead on or it will pick something right next to what you want.
Not sure if you mean camera during combat but I have had a few yells at my tv when I am fighting a group and the camera decides to play in the tall grass.
