I use just Fedora with GNOME I ditched windows because of its bad interface and UX, first I tried linux mint, liked it but I wanted more, so I installed Nobara with KDE (but quickly begun rising hyprland), my rice was almost done, than I updated my system and its all broke, after that I decided that I just want a stable DE and went to Fedora KDE spin, overtime I noticed more and more bugs and Windows style interface bothered me more and more, so I decided to stop my unreasonable hate on GNOME and try it, and I quickly loved it. Now my plans is maybe install Fedora Silverblue (or GNOME OS once it will have stable release) and run it forever

EDIT: a little bit more about my setup. I use mostly flatpaks bacuse of sandboxing, 5 little extensions that don’t change intended GNOME workflow and glfw + sdl compiled to have no window decorations (because they useless in games imo) (they not installed in system)

More precisely, it almost never does.

I don’t know any flatpak in my system that don’t use runtime (I have around 50 flatpak apps installed), or am I misunderstanding your point

Flatpak is not single binary, Flatpaks have shared runtime (For example Freedesktop, GNOME, KDE runtimes)
