Confirmed in the following Qt applications: Wallch, VLC and Qt Creator Steps to reproduce: 1. Open the application 2. Exit fullscreen (unmaximize) if maximized 3. Open any application dialog through the menu or through a shortcut (e.g. Ctrl+P for Preferences dialog) 4. Close the dialog with any way. 5. Hover your mouse where the menu should be. The menu is now gone Video demonstrating the problem: https://www.youtube.com/watch?v=QRpl1rM9gxM ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: unity-services 7.2.0+14.04.20140423-0ubuntu1.2 ProcVersionSignature: Ubuntu 3.13.0-24.46-generic 3.13.9 Uname: Linux 3.13.0-24-generic x86_64 ApportVersion: 2.14.1-0ubuntu3 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CurrentDesktop: Unity Date: Sat May 3 20:30:11 2014 ExecutablePath: /usr/lib/unity/unity-panel-service InstallationDate: Installed on 2014-04-18 (15 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) SourcePackage: unity UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: unity (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug trusty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1315717 Title: Global MenuBar hidden in Qt applications after any dialog opens To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1315717/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
