Not sure if this is the same, because I have this sometimes, since a few days.
It happens for me when I stay in the game. So for example visit a fellow or neighbour. I don't know exactly when it happens, but it happens in the game itself.The game kinda flashes sometimes, sometimes half of the screen seems black for a part of a second. Sometimes the city just looks weird, like the buildings don't have their normal size. That made me think of a laughing mirror, where you look in a special kind of a mirror and suddeny look very fat, or tall or something. The buildings look very big/weird and then suddenly have the right shape/size again. It happens fast, when you started wondering what you just saw, it is already back to normal again.
Can't describe it better than this for now. I don't have this issue on the dutch server, so that makes me think it is not my own computer.
It just happened when I visited a neighbour, but visiting other neighbours went well so far.
First I thought it had to do with the total freezing of the game, which happens often when you change tabs and then return to the game. But it also happens when you don't change tabs. I hoped the freezing would have been solved and we would have the flashes now, but that's not true, both happen.
