Typical, just after posting this I turned up the answer with a Google
search (I had tried before but obviously I got better search terms this
time). 

The answer is to restart lightdm after the system has booted and it's
showing the broken display.  Just go to a console login and do:-

    sudo lightdm restart

and everything is perfect.  

Is there any way I can fix this so I don't have to restart lightdm, i.e.
is there something I can do in the ligthdm.conf file to fix it?
