I try to tweak the Breeze Dark theme. My goal is to make it a little bit brighter (like Wonton Soup but with better font contrast) and to have an active titlebar which can be spotted easily (I often search for it because of the black on black appearance).
So I go to SySe > Appearance > Color, set Scheme to Breeze Dark, go to Colors and change Active titlebar, for instance. What I expect is that Scheme is changed to Current (works) and new settings are applied to the window (doesn't work). Can someone confirm this issue?
The colors are applied correctly when I switch between predefined themes.

PS: When I select any other theme and fine-tune something the Breeze Dark is applied completely. Plus, Default scheme looks like bright Breeze but applies the dark one.

Yes, I have this problem, too.
It's quite annoying, because you always must save your edited theme and if you change something, you must do it again and again ..

Thank you. Bug is filed under https://bugs.kde.org/show_bug.cgi?id=344380
