Created attachment 140952 [details] screeen recording SUMMARY Please watch the attached screen recording. "Keep above other windows" button is present in window decoration but it is missing from window decoration preview in Titlebar tab of Window Decoration KCM. When I drag a button to titlebar preview, "*" appears in the window decoration and "Apply" button is activated but the dragged button does not appear in the window decoration preview. Furthermore, minimize, maximize and close buttons are not visible in the window decoration preview. EXPECTED RESULT Preview of window decoration should show all current buttons and buttons dragged to it SOFTWARE/OS VERSIONS Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.22.80 KDE Frameworks Version: 5.86.0 Qt Version: 5.15.3 Graphics Platform: X11
That's bizarre. Cannot reproduce.
Fixed on neon unstable, not reproducible on Plasma 5.23 beta.
