Seems like you are hitting something invisible and your pathing is not in line with where you point; feels jerking you along. It happens in this specific area. Might be related to the lamps here or the floor in this area.
Also a side note:

These tents tend to mess up pathing and also ability targeting a lot. when you hover over them they don’t disappear fast enough where abilities often will try to target ontop of these assets or miss enemies. When you warpath in this area your warpath jerks to the side because it’s targeting this asset.
