Strange line and culling errors? (can't identify properly the source of the issue) ["solved"]

Thanks for your answer. :slight_smile:

The shadow bias is at 0.5, the default value, I tried increasing to 1 without any result.
As for the lighting, it is coming from different point lights which are very far away in the world.

I tried the Immersive mode on your recommendation but it did not show any difference.
In fact, the further away I go from the blocks, the more the issue shows.

Here is what is happening when I get a away more progressively. I will post the image links directly so that you can see it in a better way:

You can see this sort of toothed line at the back of the cube. It is moving up and down when I move forward/backward and corresponds to the sort of lines seen in the first screenshots up there.

I don’t think that resolution is the issue either as I just tried it with Immersive without any more results.
I also tried with the three types of AA available without noticing any difference.
