Yes it happens also in 3rd person mode it is just easier to see because of the camera angle. But it is not necessary to be right up against the surface. If you are next to the ground then it seems you must be closer to the wall when you look up to get the effect. If you are about 25% up from the bottom of of the wall it seems like you do not have to be as close to get the same effect.

Also if you go back to my first post you will see that I rotated the wall 90 degrees. You will not get this effect then when looking up or down but you will get it if you vary your view angle in a horizontal direction. So it seems that looking along the long edge of the poygon is where the problem appears to be most pronounced.
