SUMMARY Closing the window with your window decoration's close button does not stop the app from running. When wanting to start it again from kickoff, you get an error message. It is possible to exit the app completely with ctrl+q I have only experienced this issue with freetube which runs in xwayland mode (when using the enter picture in picture mode it shows the X logo) STEPS TO REPRODUCE 1. have Freetube running 2. close the window with your window decoration's close button OBSERVED RESULT The process for freetube remains running in the background, can be checked via System monitor EXPECTED RESULT Fully close out the program SOFTWARE/OS VERSIONS Linux: EndeavourOS KDE Plasma Version: 6.2.4 KDE Frameworks Version:6.8.0 Qt Version: 6.8.1 Additional Information I'm not sure what plasma component handles exiting applications, and wheter it is fully a plasma bug or an electron one
This may be relevant: https://bugs.kde.org/show_bug.cgi?id=477579 May be something with ksmserver
KWin only tells apps to close the windows, it's up to them to close when the last window is closed. Please report this to freetube
