@Carmelo_DrRaw I see what you’ve done to smooth the transition, thanks!
Regarding the crash, please take note that I started working on this image with the latest appimage, then downgraded to the ppa version because it was crashing after some tweaking I don’t recall anymore, then I upgraded again because of @afre tip on the Exposure slider. Not sure if this go back and forth may have inserted some inconsistency in the data. I should have notified you on the first crash, but I was focused on getting some results
