Minimap is broken

[TheMegaGamer]

I have a world of size 15,000 x 5,000, and the minimap breaks at the edges.

Yeah, can confirm, map breaks both vertically and horizontally at about ~500 feet to the edge, but only to the right and down, up and left are okay. My world size is 16800x4800, so, completely within the vanilla proportions.
