All KDE software from git master on top of Fedora 37. STEPS TO REPRODUCE 0. Don't use a custom accent color or an accent color from wallpaper 1. Open System Settings > Colors 2. Change accent color to "From Wallpaper" or a custom color 3. Click Apply OBSERVED RESULT The radio button backgrounds in the KCM change to match the window background. EXPECTED RESULT That doesn't happen. ADDITIONAL INFORMATION If you close and re-open System Settings, the radio button and checkbox backgrounds are correct again. But if you change the accent color while the app is open, they become wrong once more. Only seems to affect QtQuick apps. Bug is possibly in qqc2-desktop-style rather than here.
Should be fixed with https://invent.kde.org/frameworks/qqc2-desktop-style/-/merge_requests/389
Yup, it was indeed.
