Have a look at this:
Hope You see also what Im seeing: broken triangles black or with moire.
It is happening only with my Gopro 7 sequences. And only part of them that were made around july 2019.
It is clearly a rendering problem, because I can download orginal photo and it is not broken. Also bject detection works fine. Maybe just need to re-process them again? I could flag this kind of buggy sequence when I find them but how?
