Your demo played fine and I see the effect on that.

On this el7 box I use KDE with 'system settings' 'virtual desktops' set 
to 1.  My test box has f27 and probably the same settings but does have 
a GT_710 with the current rpmfusion 396 driver. This may be why I 
haven't seen this myself.  I could perhaps try 'virtual desktops' set to 
2 if no-one else responds, but I'm not familiar with using such a system.

The f27 GT_710 setup uses hdmi to the tv and VGA to the monitor.  Both 
boxes on recent mythtv master.
