As you can see, I only have 1 flatpak app installed, but I have a lot of flatpak runtimes installed. Are they safe to uninstall, or are they still in use somehow?

    To add to @karel's answer: The command flatpak uninstall --unused uninstalls all unneeded runtimes.

  2. The six Flatpak runtimes that are installed are being used by the DolphinEmu Flatpak app (org.DolphinEmu.dolphin-emu/x86_64/stable), so it is not safe to uninstall them.

    Assuming that you no longer have any Flatpak apps installed it's safe to remove all the installed Flatpak runtimes with a command of the form flatpak uninstall --runtime ID-of-1st-app ID-of-next-app ID-of-last-app. These Flatpak runtimes will get automatically reinstalled the next time that you install a Flatpak app from the flathub remote, so it makes sense to not uninstall these Flatpak runtimes unless you are sure that you don't want to install any more Flatpak apps.
