Nanite flickering squares

Hi all, I have been experimenting with using the mega assemblies from Vally of the Ancients in a separate project.
When viewing the nanite meshes from a large distance, it looks to me like some of the triangles are being rendered incorrectly; the attached images show that the depth is way off what it should be. These artefacts seem to be dependent on the camera’s position: when it is static the artefacts are stable but as the camera moves they ‘flicker’ (I had to disable TSR to capture the following screenshots as the artefacts were too unstable with the camera jitter introduced by this).
Does anyone have any ideas on why this might be happening and what I can do to resolve it? Thank you for your help!


For anyone else with this issue in future, I found that moving everything closer to the world origin resolved the problem.
