System Settings -> Notifications: Notifications -> Screen Saver -> Screen unlocked notification not working After the upgrade to Plasma 5.12 the script I have set in the Run command field doesn't run when the screen is unlocked. This is also the case in the Screen locked notification, and only on the Run command. Paying a sound, message popup and Log to a file all work as expected. The Mark taskbar entry doesn't appear to do anything on lock or unlock either.
This seems to have been fixed in the 5.43 update.
