SUMMARY Dock background opacity doesn't change too much with the plasma theme "Aether Dark" STEPS TO REPRODUCE 1. Change the desktop theme to [Aether Dark](https://store.kde.org/p/1245521/) 2. Change the dock opacity to 0% OBSERVED RESULT The opacity of the dock background changes very little. EXPECTED RESULT The dock background opacity changes more, like the change of the panel.
that theme is broken and I have wrote it in the comments (user psifidotos) . The shadows for panel background are missing an element needed by plasma-frameworks, shadow-center . One thing you can do is to disable Shadows for Background. It should fix this until its developers fixes this...
