The camera is child of cube, if I keep turning the cube pressing “D” all the time the camera flick sometimes I dont know why, I mean I know if I make the camera straight (not looking down) it stop to flickiring.
Hey, seems like the issue is with the scale of the parent object of the camera. I set the scale to 1,1,1 and it worked fine for me.
