Reproducible on Arch Linux (plasma 5.12.4) and neon dev unstable. 1. have two or more user accounts configured on your system 2. start plasma session using the account A 3. open system settings > user details > user manager 4. select account B on left side and click its current avatar on right side 5. select a new user avatar from the gallery 6. click "apply" button, type your password and press enter (apparently the new avatar was applied correctly) 7. do logout (sddm does not show the avatar applied in step 6 for the account B) 8. start plasma using account B 9. open kicker or lock your screen: same case of sddm, avatar is incorrect again 10. open user manager: account B shows the avatar applied in step 6
Bug persists. Operating System: Arch Linux KDE Plasma Version: 5.14.3 Qt Version: 5.12.0 beta4 KDE Frameworks Version: 5.52.0
