I use Fedora and this is how I use Flatpak as well. Some software does have some problems when used through Flatpak. I vaguely recall Blender's Flatpak version having some issues. I would also like to see more transparency with who is publishing the Flatpak on Flathub. Maybe I'm just dumb but it is not immediately obvious to me who the publisher is and whether or not this is an officially supported Flatpak application.
