Bad icon substitution for missing Oxygen icons
When set Oxygen iconset, the missing icons are substituted by Breeze icons. These icons are dark, even if Plasma theme set to Breeze dark should provide the light variants. The result is dark icon on dark system tray.
STEPS TO REPRODUCE
1. Set Breeze dark Plasma theme
2. Set Oxygen iconset
3. Set DND mode
DND icon (striked bell) on the systray is unreadable.
White icons on dark panel should be provided from Breeze dark iconset.
