so looking at link provided here https://groups.google.com/g/natron-vfx/c/89V09-uzblc https://github.com/NatronGitHub/openfx-supportext/blob/master/ofxsMerging.h it seems divide provided as operation only on color channels? And what we do with alpha in this and similar cases? or may be I read wrong source again ....

at some point GIMP also has layer math problem, see https://bugzilla.gnome.org/show_bug.cgi?id=162395 namely different visual results in different versions and then on top of this question about old project files ....
