I’ve been involved with Linux for a long time, and Flatpak almost seems too good to be true:
Just install any app on any distro, isolated from the base system and with granular rights management. I’ve just set up my first flatpak-centric system and didn’t notice any issues with it at all, apart from a 1-second waiting time before an app is launched.
What’s your long-term experience?
Notice any annoying bugs or instabilities? Do apps crash a lot? Disappear from Flathub or are unmaintained? Do you often have issues with apps that don’t integrate well with your native system? Are important apps missing?
Its quick and easy to install a flatpak which is the latest stable which is a godsend when the versions available through package manager are years out of date. Not everyone can compile from source or add an additional source repo. My only big issue is how bloated flatpaks are size wise and where stuff gets installed in my file system.
