How to reproduce: System Setting -> Keyboard Settings Choose any wanted layout or setting and click "Apply". Keyboard layout or other settings are now changed! You can click "Cancel" in the Authentication window, because the settings have already changed Expected behavior: Keyboard locale not changed until user entered authentication information. What happens: Keyboard locale changed I tried this in an older version of Manjaro and it was still like this. About a month old one, if that helps. Currently on System Settings version: 5.11.2 KDE Plasma version: 5.11.2 KDE Frameworks version: 5.39.0 QT version: 5.9.2 Kernel version: 4.9.58-1-MANJARO 64bit
