Comment 2 for bug 1598583

I'm seeing what sounds like this same issue, but it is hard to tell because the original zip file is no longer available.

I'm stitching 360 spherical panoramics taken from a DJI drone. All images are present, overlapping and appear fine in the preview, but after final stitch, there are black/grey areas where an image has been missed. Usually one, sometimes two. They seem to be near the edge of the image.

I can confirm that --primary-seam-generator=nft fixes the issue.

I'm using:
