Finishing up takes forever

no upscale, just recover low-quality image takes forever. no indication whatsoever how far it has come. after an hour or so it is finishing, but not finishing up. I cannot do anything but cancel.

Yep. Same here. The upgrade to 8 is a disaster. We need instructions on rolling back to 7.4.

I have the impression that gigapixel made no progress at all and it was only making a preview. I canceled it after 1,5 hours on my macbook pro M2. I also find the interface really confusing, no start or stop button and no progress indicator.
