Created attachment 136252 [details] CSD GTK window with missing buttons SUMMARY The close, maximize, minimize buttons are invisible on CSD GTK windows with the Breeze-gtk theme. STEPS TO REPRODUCE 1. Start a Plasma session with a clean profile 2. Launch a CSD GTK application (Simple-scan in my example) 3. The close, maximize, minimize buttons are invisible but are clickable. 4. Delete .config/gtk-3.0/window_decorations.css and restart the GTK application. The window buttons are now visible, but they will become invisible again on the next session restart (because window_decorations.css will be recreated). OBSERVED RESULT The close, maximize, minimize window buttons are invisible. EXPECTED RESULT They should be visible. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Archlinux / Plasma 5.21.1 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2 GTK version: 3.24.26 ADDITIONAL INFORMATION Oddly enough, the GTK window decorations display correctly on an older profile, and the contents of window_decorations.css is exactly the same.
Oh damn sorry, I rebooted my computer, tried again with a clean profile, and now it works...
