Trying to get rid of <Grid> jitter

[geoff-harper-qii]

What is your question:

I'm getting a fair bit of jitter on the Grid component. For reasons out of my control, everything is placed at an offset to something to the tune of 500_000, 300_000, 50. I realize this is likely to cause jitter but I've grouped everything in the scene and placed the group at an offset. The grid is locally positioned around 0, 0, -30. My solid meshes in the scene don't get any problems with this fix but the Grid seems to remain jittery. I tried putting everything at 0, 0, 0 world coordinates and the jitter unsurprisingly disappeared. Is there a way to resolve this or is there some fundamental difference between solid meshes and the grid's line mesh? I'm afraid zeroing out the world positions is out of the question
