Comment 23 for bug 721136

update: the parameter "--primary-seam-generator=nft" does seem to make the problem more rare, but right now I have a 360° panorama with a targeted output size of 119448x6727 pixels which even though I tried stiching 3 times always gave me black holes.

I'm currently trying the parameters @isaacq suggested: "--fine-mask --primary-seam-generator=nearest-feature-transform" but that slows down enblend a lot. Already running for over 6 hours.
