The issue had to do with that my app icon’s resolution was too big for Gnome/electron to handle. The Mac OS icon of about 1800x1800’s resolution is too large. Around 500x500 does work!

Perhaps a small warning could be shown if the icon resolution is too large?

Otherwise, a static text with “Make sure your icon size is accepted by your OS/desktop environment, otherwise it might not show correctly” or something along those lines could be nice.

thanks. We are not going to handle hedge cases involving this not working. This functionality is mostly handled by electron is OS dependent.

I don’t know how you’re getting this to work at all. I’ve tried it with Ubuntu 20.04, 22.04 and 24.04, with the deb or with the appimage, and the custom app icon has never worked for me.
