SUMMARY The Media Player plasmoid is not working, seemingly due to the Qt version. STEPS TO REPRODUCE 1. Log in 2. Click the blue icon in the system tray OBSERVED RESULT The normal Media Player plasmoid isn't visible in the system tray. Instead there is a rectangular blue icon and when clicking it, the following message is shown: file:///usr/share/plasma/plasmoids/org.kde.plasma.mediacontroller/contents/ui/main.qml:13:1: The plugin '/usr/lib/x86_64-linux-gnu/qt6/qml/org/kde/plasma/private/mediacontroller/libmediacontrollerplugin.so' uses incompatible Qt library. (6.7.0) [debug] EXPECTED RESULT The Media Player plasmoid should work as usual and show its normal icon. SOFTWARE/OS VERSIONS Linux: 6.5.0 (available in About System) KDE Plasma Version: 6.0.3 KDE Frameworks Version: 6.0.0 Qt Version: 6.7.0 ADDITIONAL INFORMATION
I got some new updates in Discover, and after installing them, logging out and logging back in, this issue was fixed.
