Grass Tool Cull Distance Bugged

I can confirm the bug is there and I have created a bug report here: Grass tool culling broken - Programming & Scripting - Unreal Engine Forums

Grass Tool isn’t culling the meshes properly. Meshes happen to appear/disappear in quads instead of appearing/disappearing individually.
This bug might be specific to some specific landscape sizes only i.e in my case 1009x1009.

Repro steps:

  1. Create a landscape with the given settings as in the image.
  2. Setup a material with grass node.
  3. Use a mesh in grass node with high density.
  4. Reduce cull distance to 5000.
  5. Fly forward/backward to see the meshes culling.

Landscape settings:

Please don’t let this one be backlogged like the last few I’ve reported.
