Did this ever work in the past? If so, when?

Hello Nate,
Excuse me for the late reply. It has worked on Plasma 5, but for some KDE applications like "System Settings (Icon only)" , Konsole, Dolphin, etc.

Since this is a 3rd party addon and there have been breaking changes to plasma 6, I think this addon (or the Lightly addon this depends on) needs to be ported to Plasma 6.

Please reach out the the authors of your 3rd party addons.
Comment 4 Nate Graham 2024-02-26 17:56:21 UTC 
The issue here is that the 3rd-party theme broke in Plasma 6 because the ability to have a a color scheme with transparent colors broke.
