Update: When I look at .config/kwinrulesrc, the rules are there. Dot-config directory has perms 700, files in it 600: $ cat kwinrulesrc [$Version] update_info=kwinrules.upd:replace-placement-string-to-enum,kwinrules.upd:use-virtual-desktop-ids [09f4baee-8ebe-4b0f-8ee7-d5e29dcf7a61] Description=Oclock On Top above=true aboverule=5 wmclass=clock wmclassmatch=2 [c6a04145-ec8d-484b-b12c-f3ce3cac698d] Description=Oclock above=true aboverule=5 wmclass=clock wmclassmatch=1 [c87a5e39-852c-4796-9984-e0519e08f434] Description=oclock above=true aboverule=5 wmclass=clock wmclassmatch=1

The rule getting deleted after it's applied is expected behaviour. The rule policy is "Apply Now", which means it's a "fire and forget". After it gets applied, it will get deleted by KWin, similar to what "Force Temporarily" does. To make the rule "stick", the policy should be "Apply initially" instead. I know this not a very clear indication of what it does, so I'd be happy to change the text to make this more clear (to something like "Apply temporarily" and add maybe some hint like an icon. If you hover over the policy items in the combo box, the tooltips indicates the rule will be deleted after applied (while the text can also be not super clear). The config file is actually indicating that there are no rules (there should be a "[General]" grup that list the rules for them to be picked). That there are still "leftovers" is actually another bug (https://bugs.kde.org/show_bug.cgi?id=446381), although it has been helpful in this case.
Thank you, Ismael ! Now I understand how it works
