STEPS TO REPRODUCE 1. use any of the default global themes (Breeze, Breeze Dark, Breeze Twilight) 2. open System Settings > Appearance > Window Decorations 3. OBSERVED RESULT no window decoration is highlighted EXPECTED RESULT current window decoration should be highlighted SOFTWARE/OS VERSIONS Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.20.80 KDE Frameworks Version: 5.77.0 Qt Version: 5.15.1
Can reproduce.
I looked at it and the defaults that the kcm writes are [org.kde.kdecoration2] library=org.kde.breeze theme=kwin4_decoration_qml_plastik while it should be [org.kde.kdecoration2] library=org.kde.breeze So the kcm thinks it has been changed but can't find the current theme. But it works since breeze doesn't support different themes.

it's still reproducible. Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.20.80 KDE Frameworks Version: 5.77.0 Qt Version: 5.15.1
Does Neon build plasma-workspace with breeze kdecoration available?
