I see it. I've looked over my testvideo, but I don't think I have it. Now, that is, I just did this one little video with it.
In my testvideo I mixed two clips of two 360 cams with two different resolutions by the way. The one on the scooter was with a XDV Pano View (2560x1280) the one on the grass is of my LG (2880x1440).
The Pano view has only one lens, so a black disk below. What I did notice is that the black disk stays rigid in the unstabilised video, but bounces a bit in the stabilised video.
I believe I know where the vortexes may be coming from. If you stabilise a normal video with software, often it crops the video a bit so it has some room to maneuver when stabilising. In a 360 shot you cannot crop the video, or the sphere would not be full anymore. My guess is it tries to overcome this by jarring a bit at the top/bottom of the equirectangular, which could result in these vortexes (nadir/zenith are just single points/poles, but cover the full top/bottom of the equirectangular).
Not sure this is it but I think I might be on the right track.
Anyway, I'm VERY happy with the stabilising. I almost next month bought a Guru stabilizer, but I keep that money (about €300,-, already accounted for the €70,- PD upgrade) in my pocket for now. It was juggling my money anyway, so better to postpone it. Now I can do moving camera shots and don't worry too much about shaking shots.
Just check out this difference: I just quickly re-did one of my latest videos with the new stabilising.

I'm stunned, this is fantastic.
No weird nadir things happening here. I stabilised about 20 or so smaller clips individually here.
