SUMMARY *** I have a couple of Chrome Progressive Web Applications (PWAs) installed: Teams and WhatsApp. These appear with no file menu, but when I double-click the top border - I'm not sure whether this is still the Titlebar - the windows go to full screen, whereas all other windows I have configured to 'Shade'. *** STEPS TO REPRODUCE 1. Install Chrome PWA 2. Click on top border 3. OBSERVED RESULT Window goes full screen EXPECTED RESULT Window will 'Shade' (as per configuration in System Settings.Window Management.Windows Behaviour.Titlebar Actions.Double-click.) SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: KDE Neon 5.27 (available in About System) KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.106.0 Qt Version: 5.15.9 ADDITIONAL INFORMATION Graphics Platform is X11
Please report the bug to Chrome. Its PWA uses client-side decoration, about which kwin can do almost nothing.
