64bit Mac Client - Ground "waves"

Date & Time: July 9, 2019
Frequency: All Times
World name: Gilgamesh
Character name: Ozan Hikayeci
Retainer name: N/A
NPC name: N/A
Monster name: N/A
Class/Level: N/A
Party or solo: Both
In-game time:
Area and coordinates: Several, example: Amh Araeng x21y10
Housing: n/a
Steps:
1. When encountering long flat areas of floor graphics (ie the train tracks in Amh Araeng), the tracks will jut out from the ground toward the camera, cutting in front of and through other graphics.
2. This also happens in other environments randomly.
3. It appears when I rotate the camera, that there is an invisible bump that the floor graphics are trying to place themselves on top of, creating a ramp on both sides of the "wave" or "hump" and a flat top.

I think I've been seeing this too? I most often see it with water, though! It actually sometimes hides aoe markers or otherwise impedes gameplay :x. I've even seen it in pre-rendered cutscenes! I haven't reported it myself though, because I suspect it may be a known bug (there was something about occlusion culling issues in the 64-bit client?).

If my issue is the same one, then the recent update has actually managed to make this worse.
