I use breeze light, but prefer a dark konsole. Historically, I've made a window rule for konsole, but now use the built-in setting (from the drop-down menu) to set breeze-dark. This is minor, but when I hit "close," I can briefly see it change back to breeze (light), before / during the closing animation. STEPS TO REPRODUCE 1. Set breeze-dark in konsole's settings 2. Close konsole 3. Briefly witness the window border change to light, before closing animation completes SOFTWARE/OS VERSIONS Linux/KDE Plasma: 6.0.0 w/ Qt 6.6
It will be fixed after updating to Qt 6.8.
