Public bug reported: [The bug] When the integration of the app menus into the window title bars is turned on, call of any dialogue from the menu leads to disappearance of the menu. After that, the window title bar displays only the application title string. The main menu cannot be seen and cannot be accessed until you switch to another application and then return. The bug is observed only for unmaximized windows. The main menu of maximized windows works fine. This bug is observed only for Qt applications. I have “succeeded” to reproduce it for VLC, Gwenview, digiKam, Krita, Calliga, VirtualBox, GoldenDict.
[How to reproduce] 1. Make sure that “Show the menus for a window” parameter (System Settings -> Appearance -> Behavior) is set to “In the window's title bar”. 2. Start any Qt application, say, one of mentioned above. Let it be, for example, Gwenview. 3. Unmaximize the app window. 4. Activate any dialogue from the main menu. For instance, File -> Open... or Settings -> Configure Gwenview... 5. Press Cancel to close the dialogue. 6. Hover the mouse pointer over the window title bar. [What is expected] The app menu should appear and be accessible. [What happens] The app menu is not shown. Only the application title is displayed in the title bar.
