SUMMARY *** I have an application that I do not want to show up in the taskbar. So, I click on the little icon in the top left of the window frame, and then go to application-specific settings. Then I add a property for all windows to skip the taskbar. I first apply it now, then stick it to apply initially. This seems to work only for the session. Once I reboot, the property for this application is gone. *** STEPS TO REPRODUCE 1. Click on application icon in window titlebar of application 2. Select "More actions" then "Application specific settings" 3. Select "All window types" and exact match for the application 4. Add property "Skip taskbar" 5. Apply. See that indeed this application disappears from the taskbar. OBSERVED RESULT Upon reboot, this applicaiton is showing up in the taskbar again! This is an application that is auto-started. It's my password manager, so I want it running all the time, but I don't want it eating up the slot in the taskbar. EXPECTED RESULT I expect this special application settings to be persistent.

Thanks for your report. To try and understand what is happening, it might be that "Apply" is not catching the application start-up, specially if the app changes the window properties on start-up Can you try to set the policy to "Force"? Also, if you can attach the file ~/.config/kwinrulesrc that can be helpful. Also check in Systemsettings (Window Rules) if the Rule you set is still stored. Thanks!
Hi Ismael. Thanks for looking at this. It is good to know some tricks to try. However, after trying several times, and the application always forgetting it's settings, something weird happened. After the most recent reboot it suddenly started remembering it's settings. It's the weirdest thing ever. I'll give it a couple of reboots, and if it keeps on remembering it's settings, I'll close this report.
This problem is now completely gone. Since this is a rolling update system, there was probably an update that fixed it, but I would not know which one. Thanks, everybody, for looking
