I've added a note to the changelog about the minimum recommended GTK version (https://github.com/PintaProject/Pinta/commit/4ab91d4b6ae15900ee36bf4e9d747a96bff59854), for the issue mentioned in comment #2.
I don't think there's too much we can do as a workaround, and it should have minimal impact since the snap and flatpak packages will have newer GTK3 versions.
