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?
My experience with flatpaks has been mostly good. I tend to opt more towards .deb based apps, with flatpak being a fallback option. With that being said, the Pycharm Pro and Spyder flatpaks don’t run well at all on my system, with Pycharm being too heavy, and Spyder crashing due to Kvantum incompatibility.
