Nordic-Solid styling of Plasma panel

[miquecg]

I've switched from Nordic theme to Nordic-Solid and while windows are now opaque, Plasma panel is still semi-transparent. How can I change that? Maybe is just a matter of unticking a box in Kvantun manager... To me it looks like only the Darker variants have a solid panel.

For the record I have installed:

• Plasma theme
• Aurorae theme
• Kvantum themes (normal / solid)
• Nordic color scheme
• Icons
