SUMMARY Windows title bar vanish on changing from a fullscreen app to other with "Alt + Tab". Two monitors configuration. Playing video while it happens. It happens very often in this scenario. STEPS TO REPRODUCE 1. Playing "Zero-K" full screen (it uses mono-basic package, for reference) in (HDMI) 2. Playing a video not full screen in second monitor (DVI) 3. Change from Zero-K to other opened desktop application (Firefox, for example) OBSERVED RESULT From time to time, while changing to other application, all windows title bars and decorations are lost. There is no way to move, close, minimize any windows and application panel is not accesible. "Menu" main Plasma button IS accesible. Keyboard is not responding, so I need to click "Menu, Restart" or "Menu, Close session" and enter in Plasma again. I don't know if it happens with other games at full screen. EXPECTED RESULT To NOT lost windows tible bar nor keyboard responsiveness. SOFTWARE VERSIONS (available in About System) KDE Plasma Version: 5.12.6 KDE Frameworks Version: 5.46.0 Qt Version: 5.9.4 ADDITIONAL INFORMATION
