The linux mint project is hard at work with a soft fork (It derives but will have 100% compatibility with libadwaita apps, enough so it's just a change of header files) of libadwaita that allows theming better handled.
It's version is the same as 24.04 (1.5) and it built perfectly on trixie. https://github.com/xapp-project/libadapta Now, could this be a drop in replacement for libadwaita? Instead of using the GNOME sources, use the xapp from github sources? Or maybe make a patch that diffs the mint differences from GNOME's?
