Background disappeared

When I have my browser full screened my desktop and app dock disappear and it becomes black, I am still able to open apps via the windows key but otherwise it is quite frustrating.  Should note I have a external monitor attached with a laptop which is connected which hdmi, with the screen closed and then this happens, when I open the laptop screen it gets fixed. 


STEPS TO REPRODUCE
1.  leave the computer running for a while possibly 3-4 hours 
2. have a application full screened the whole time (haven't tested if this matters)
3.

If you right-click on the black background, what happens?

Did you at any time have no screens active? As in, laptop lid closed, external screen turned off or asleep?
