backdrop and alt-tab

[Ludovic Thébault]

Hello,

I've a stack with decorations sets to empty, the menubar is invisible  
and a backdrop hide the desktop.
If i select an other application with alt-tab (on windows) or cmd-tab,  
or space (on macos x) and, after, i come back to my rev app, i see  
only the backdrop. I need to set the backdrop to none, or show the  
menubar to replace my windows at the top.

Any workaround ?

Thanks.
