We can try lifting https://github.com/flathub/de._0x539.gobby/blob/master/gtkmm.json, which I copy-paste between about 5 different apps at this point…

OK, interesting, it really has both GTK 3 and GTK 4 support.

Transmission 4.0 has GTK4 support it links against gtkmm-4.0 https://github.com/transmission/transmission/blob/1f1e614f9975399f5c5e847c76f4f61104649726/CMakeLists.txt#L287

(Might need to force GTK3/4 with USE_GTK_VERSION since I think the SDK has both.)

i did that locally, still same error with glibmm

Try with the following versions:
thanks! I'll try with these

is there some rule about compiling packages because transmission is giving latest binaries in their repo now

[wjt]

I'm not sure it's written down but it is, at least, strongly preferred for apps to be built on Flathub.

This PR is mixing stable and unstable package releases. Read the documentation for each package.
If you don't want to bother doing that, then the principle is that GTK/Gnome's odd releases are unstable. Though I think there's a minimal glib version matching for packages of the gtkmm project, and glib comes from the runtime.

Don't use binary releases, it's a bad idea. You'll miss important Flatpak related changes, like the Fontconfig patches, and application developers are usually too lazy to properly build and package features that they don't care about, e.g. IM modules (see the Calibre's monstrosity binary release).
