For eg. I installed Blur-glassy theme today to check with all options selected in my Fedora 40 installation. Still I needed to install the blur option separately and colors too. After everything still Dolphin and Discover do not look anything like the picture shown.
I have seen this while trying out many themes. They either partially deploy or sometimes not.
Is it because they were built for KDE 5 and this is 6 or something?
I got it installed, not sure if it was nature of theme or if I did it correctly. It felt really off to me, luckily it was on a test user which I deleted now. Installing and configuring Kvantum felt like blindly groping in the bathroom with soap all over face.
I won’t be experimenting with it anytime in near future.
Sad to hear you had that experience. Someone posted some blog posts about complete KDE themes here a while back. I had very good results following the instructions in those blog posts. Each one had icons, window, plasma, gtk, wallpaper, and whatever else was needed. I stuck with “shades of purple” for ages, which would normally not be my first choice of theme.
Here’s one of the posts. The series was called Off-Theme.
