Created attachment 195136 [details] Screenshots My distro (fedora rawhide) upgraded to kf6-6.29. Since then, my service menus using `X-KDE-Submenu` no longer work. I have a root action submenu. When I open the context menu configuration, the submenu and actions appear in the settings. However, nothing appears when using the mouse. If I remove `X-KDE-Submenu` from the `.desktop` file, the actions reappear in the context menu, proving that the `X-KDE-Submenu` option is no longer being recognized.
I set up a machine with kf6-6.28, and my service menu worked again in Dolphin. After updating to kf6-6.29, it stopped working.
I confirm this degradation. There are no submenus specified in the "ServiceMenus" user files. If you comment out the line with "X-KDE-Submenu", all the items from the submenu appear at the root of the menu.
I also confirm this bug.
A possibly relevant merge request was started @ https://invent.kde.org/frameworks/kio/-/merge_requests/2384
Can you post a .desktop file that I can use? I want to be able to reproduce this as I'm the one who broke the submenu.

I can confirm that the patch suggested in comment 4 resolved the issue.
