Message:

FE/Qt: bugref:5978: Workaround for UIMiniToolBar which allows to avoid unwanted hiding because of Qt 5.6.1 for X11 bug about automatic mouse-leave event on screen borders; Besides that, this is a good way to keep the tool-bar visible while the mouse is moving through the desktop strut till the real screen border.
