SUMMARY Changing default language in "Region & Language" should not require and propose a full system reboot. Logout and Login is good enough. STEPS TO REPRODUCE 1. open System Settings and choose Region & Language 2. Add or choose a new default Language 3. Observe the action notification OBSERVED RESULT System Settings notification text is: Changes will take effect the next time you log in But (imho more prominent) Button Text is saying: Restart now EXPECTED RESULT Button Text should align with info text: "Log off now" SOFTWARE/OS VERSIONS Linux/KDE Plasma: neon KDE Frameworks Version: 5.114, 6.0.0
