GearVR - Black edges when rotating fast

Unity Engine
1

I say “fast” but you really don’t need to rotate the head very fast to see the effect.
It’s difficult for me to find the correct keywords for this specific issue this time ^^, that’s why I’m asking here.

After rotating the head on the GearVR, I can see black edges for 0.1~0.2 ms before the camera update and remove them.

(images that reproduce the issue without the stereoscopic view, but the problem appears only on the GearVR for a real test)

Unity 5.4.3p1, APK was built for a Galaxy S6 Edge (not signed, with occlussig certificate for the S6), GearVR2.

Well, that was because I was on a scene with low FPS and bad settings. I have to work on this !
