The file system was not unmounted cleanly so the dirty bit is 1 -> windows tells you to check the drive. This clears the dirty bit even if nothing was wrong.

Not the same thing. With session saving I don’t have configure anything.

KDE + wayland on Tumbleweed gave me this experience.

Wayland has at least one deal breaker for me. It doesn’t remember where my windows were at logout when saving the session. I have six virtual desktops and have specific windows in certain desktops. Putting everything back where they belong after each login, no thank you. Until they add that I’ll stick to X11.

If developers want to make a desktop application they should use proper cross platform desktop frameworks like QT or GTK or even JavaFX instead of a webpage disguised as an application.
