[d3d8] Railroad Tycoon 3 - zoomed in terrain shuffle

[WinterSnowfall]

This is going to be a rather hard one to describe, so I've captured a video. The TLDR of it is that when scrolling through some of the closest zoom levels on the game map, the terrain textures sort of shuffle around in a crazy dance.

I've captured a trace, but since the game does "wonderful" things with buffers, apitrace has mostly caught garbage. The issue can be seen in the trace as well though, among the madness.
