The titlebar_buttons package tries for some reason the access using GSettings the global dconf configuration database (which the flatpak doesn't have access to). GSETTINGS_BACKEND=keyfile tells GSettings to use local keyfile configuration backend instead.

Here I have some logs

If this is a solvable upstream bug, i can open an upstream issue and mark it as a temportal workaround in the commit message.
