Freelook snaps horizontally

Hey there!
I am playing around with freelook cameras,
I noticed that when rotating around an object, when the camera gets near one of the 9 horizontal directions,
the camera immediately jumps (or snaps) to that direction, breaking the smoothness.

this behavior is weird, I tried playing around with the variables but no luck,
I also completely removed the dumping and it didn’t seem to affect this issue.

here is a video showcasing:

notice that it happens on all 3 rigs, but most noticeable on the middle one.
Thanks in advance!

Sorry, but we cannot see the video. Can you post it again?
