After I selected either the Breeze Dark theme or the custom theme I downloaded (Arquetype), the background of the main panel doesn't change from the regular Breeze theme. Also when I switch from the Oxygen or the Air Theme to Breeze Dark or Arquetype the panel background changes to regular Breeze background. I tried restarting, re-logging and experimenting with the appearance settings and nothing seems to be working. I also had this problem with KDE 5.2 Reproducible: Always Steps to Reproduce: 1. Open Desktop Themes in appearance settings. 2. Change to Breeze Dark theme. Actual Results: The theme changes but not the panel background. Expected Results: The selected theme is applied everywhere, including in the panel.
Same. Shift-ALt-F12 every time brings the dark panel back. Very annoying. Intel Graphic
