Update by [Minecraft] Mega_Spud (Jay Wells):
When travelling in a minecart, as the cart turns around a corner, black lines will appear on any blocks that are directly adjacent to the rails as you travel past them.
Steps to Reproduce:
- Ride a minecart on a rail that changes direction
Black lines appear around the edges of blocks as you turn
The blocks shouldn't render any differently
Screenshots/Videos attached: Yes
A very annoying thing is happening with the rail and the minecart, when I'm inside it the edges of blocks around it turns black!
