Constant blinking/flashing in Capital City

Ok so I thought I would cut corners by posting the problem here first because pretty often, someone from the in-game help normally sends us here to post about whatever problem it is that they can't fix and their developers read posts here.

Really? 

I bit the bullet and contacted help and somebody got back to me with an absolutely laughable response.

Customer Disservice at it's best, completely ignore the problem, respond about a completely different issue that I am not having.

Please see attachment and tell me this is all a bad dream
