When I leave a tunnel and there's water after the tunnel, the water is absent until I reach the tunnel exit block. Then the water suddenly is there (see the two pictures, before and after). It seems, the graphic engine doesn't bother with water during tunnel passages (because there is no water in tunnels, of course), but the time to resume water calculation comes to late, especially if you have a downwards street before the tunnel exit which allows a wider look ahead what's following after the tunnel exit.
This occurs with the new water expanses and the old water deep down in the canyon as well.
