The bottom part of a building on the big multi-lane straight of South City (Chicane at least, haven't checked other configs) has the wrong Z index*, making some other things like the fence visible through it.
(*thinking about it further, it seems more like an alpha problem rather than z-buffer, like the building is incorrectly set to alpha and/or only alpha objects are visible through it)

I already reported it in test patch before 0.6H, but it's not fixed apparently, hope Scawen will work on it for in the futures test patchs.
