@danny @kev it is less efficient then apt. Flatpak apps run completely independent from the system libs. A runtime is the base system of an app. But there are many runtimes and the most popular are three: GNOME, KDE (it is used for many Qt apps too) and Freedesktop runtimes. LibreOffice uses Freedesktop and Telegram uses KDE. For example, Firefox and LibreOffice run on the same Freedesktop runtime so the answer is yes for them.
