fail to show all windows from all viewport/desktop
Lubuntu 14.04.1 with LXPanle 0.7.0 and compiz
Remarks on Compiz: Plugins such as 'Desktop Cube' and 'Desktop Wall' are incompatible with standard workspaces. They must use Compiz's viewports. As of Compiz 0.9.11 (revision 3857) the 'Number of Desktops' option (in general options/Desktop size) has been removed from CCSM.
