How can I make the 3D cube background transparent in KDE Plasma?

The image below shows a comparison of the 3D effect in GNOME and KDE.
In GNOME, the background is completely transparent, allowing the desktop background to be seen behind the cube. However, in KDE, the background is black. How can I make it transparent?
I’ve tried using Kvantum themes, but it didn’t w
ork. What are the settings and steps involved?


Not sure where they are stored (only had a quick look) but I would look for the config files for it and see what is possible to change (if you find them link the location and I will have a look and see if I can see anything)
