There is a problem with the character's perspective or screen tilt.

Characters on a slope or on uneven ground near a wall will have strange screen shake.

I get it too. Also see other players leaning sometimes too.

Haven't you noticed? On slopes or uneven areas, the character perspective can appear to have a very unnatural swaying motion. This movement appears abnormal.

But not all terrain is like this, only a few occasionally.
I know planetside2 like the back of my hand, and it's hard for such bugs to escape my observation.

Drinking too much

very boring concerns will not even be corrected in tomorrow's update no matter what the dev sometimes plays their games it is very boring this bug

lol noticed this for a week or two now as well.
