How to reproduce :
1. launch an application
2. minimize this application
3. window application freeze
4. must press the start button to minimize the window
5. then the window is minimized and the menu "reboot, exit..." appears.
6. this doesn't happen if there's at least another window and doesn't depend on the application (nautilus, firefox...).
I should notice that I had this problem with 15.04.
Moreover since 15.04 no icon and folder appear on the desktop (even if the desktop folder is not empty) and I can't change the wallpaper.
