I checked both on RP and on 6D, the effect is here, and only at 16mm, rotate the zoom ring slightly and it magically disappears suddenly.
The lens was functioning normally, the same day I took photos at 16mm that were normal, I swapped for 24-105 took some photos then came back and as soon as I put it on the camera, in the viewfinder I noticed this effect at 16mm (did the lens fall to the ground while I was busy shooting?), it is stable at all apertures doesn't change.
