SUMMARY I installed new Window Decoration by "Get New Window Decoration" (Wilow Dark and another), clicked "Close" and noticed that grid view has not been updated with newly installed decorations. Only when I clicked other option in left side bar for example "Color", and back to "Window Decoration" then found updated grid view. STEPS TO REPRODUCE 1. open settings -> Window Decoration 2. install any by clicking "Get New Window Decoration" button 3. "Get New Window Decoration" 4. Check grid view OBSERVED RESULT missing installed Window Decoration EXPECTED RESULT newly installed Window Decoration should be visible in grid view just after clicking Close in "Get Window Decoration" window SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Plasma Version: 5.24.80 KDE Frameworks Version: 5.91 Qt Version: 5.15.3 ADDITIONAL INFORMATION
Can confirm, the grid view does not update when adding or removing window decorations.
