Created attachment 115541 [details] The bug in the menu for gimp SUMMARY In Gtk applications like gimp, checkbox options appears without the checkbox in the global menu (it's correct for the appmenu in the window decoration bar). So we can't see option status in the menus of the global menu bar. STEPS TO REPRODUCE 1. Open Gimp 2. Click on "Windows" menu on the global menu bar 3. Option "Single-window mode" doesn't have a checkbox (which is expected) OBSERVED RESULT Options with checkboxes appear without the checkbox. Tested with libreoffice, gimp, ... all have the bug EXPECTED RESULT The checkbox should appear SOFTWARE VERSIONS (available in About System) KDE Plasma Version: 5.14 KDE Frameworks Version: 5.50.0 Qt Version: 5.11.1
*** Bug 399609 has been marked as a duplicate of this bug. ***
In 5.14.2 version: Problem solved for QT applications (dolphin, vlc). For some gtk applications (libreoffice, gimp), the problem persists. But if I minimize then restore the application (or switch to another application, then go back to libreoffice or gimp), the checkboxes are now present. But for other gtk applications (thunderbird, firefox), the problem is solved like qt applications. Is it due to different gtk version (2 or 3)? So, problem only partially fixed...
For Gimp I request the "windows" menu, then look up the relevant action which does not exist. Then I get an action change event which adds it, I signal a menu item change but in dbusmenu-qt the toggle-type cannot change, so it ignores that it now has a checkbox. Not sure on which side the actual bug is on, though.
