The plasmoid with the error.
Click the Media Control icon shows an error message instead of the plasmoid (Image attached).
STEPS TO REPRODUCE
I haven't done anything special really, when I saw that the media player icon appeared I simply left clicked on it.
An error message:
Error loading QML file: file:///usr/share/plasma/plasmoids/org.kde.plasma.mediacontroller/contents/ui/main.qml:162:34: Type ExpandedRepresentation unavailable

file:///usr/lib/qt/qml/org/kde/plasma/components.3/ComboBox.qml:191:13: Cannot assign to non-existent property "showShadow"
The actual media control panel should have appeared

I'm terribly sorry if it's not the right place to report this, thank you.
> Cannot assign to non-existent property "showShadow"
ButtonShadow.qml has the showShadow property and this file hasn't changed in 2 months. I suspect a diwnstream patch is causing this; it's all correct in the code that I can see in our git repo. Please report this to the Manjaro devs. Thanks!
Restored back to normal after restart. :(
Sounds like a local issue on your machine after upgrade then. It's generally recommended to reboot after any big update. :)
