Description jonas.harer 2025-11-04 17:55:15 UTC 
SUMMARY
Installing flatpaks makes them automatically the default app for things that should still be opened in other apps

STEPS TO REPRODUCE
1. Install a traditional (not immutable) distro (e.g. Arch)
2. Make sure .py files are opened in Kate (installed using the package manager)
3. Install another editor using flatpak (e.g. org.gnome.Builder)
4. Open the same .py file from Dolphin

OBSERVED RESULT
It opens in GNOME Builder

EXPECTED RESULT
It should still open in Kate

That is how this is meant to work?

If you don't have kate manually configured as editor for py files then any newly installed application will take over the file association. Only when you explicitly configure a default will that stop.
