If you mean the one that has just dropped, then yea I had the same issues originally.  I just closed the game down completely and did something else for 20 mins.  When I came back it is now back to normal.

I attributed it to the game/server still updating or needing a reboot

Very sad experience ever. I even didn't face this kind of screen issues yet. 

Sorry  for  the  inconvenience.  On  the  bright  side,  at  least  it  happened  when  the  Plarium  employees  were  getting  to  work  and  not  on  a  weekend!
