I was actually building something that only had 1 level above ground and nothing else. As I tried to rotate the camera from one side to the other it went all out crazy on me, from the start of building that lot. I haven't even tried actually playing it yet, because build mode drove me nuts already.
I still don't see a problem on lower levels of that lot, but I was able to experience it to a great degree on the 4th floor of a structure I added. I created a video of it to demonstrate the issue and give devs an idea of why the bouncy camera is a problem for builders (and players).
That is a crystal clear video. My lot was on the ground floor, the building was as big as the lot (minus a 1 block border on each side ofcourse) and the highest types of walls. No 2nd or higher floors. And I already had this issue. It's really hard to focus on what you are trying to build when the camera swings in all directions like that. And as said above, in City Living it happens to on appartments and penthouses if you are working near the outer wall, allthough it is less sickening then this one.
