I can't test right now, but maybe it's from because some objects don't have scale applied, so epsilon issue perhaps.
The ring noise i got one time with cornell scene when i limited max epsilon to 1e-6

:arrow: The source of the issue is the3D mapping of the checker board. If set to local stripes and rings happen.
If set to global, needs different scaling, the rings do not appear.

The effect is not related to: epsiolon, type of light source, HDRI, Sky. :geek:

Please check the 3D mapping of textures. Thank you,

I think the global 3D mapping automatically applies a tiny offset, but the local mapping does not (?).
The fundamental problem is that the checkerboard texture is exactly intersecting the plane with one of its "sides". It's a bit like having two faces exactly on top of each other.
You can fix it by applying a bit of translation in a 3D mapping node.

By the way, I can't replicate the problem here - maybe it has something to do with scale after all? Can you upload the scene?

Blender crash when using Background image in LuxCore Imagepipeline in both final and preview render.

I can not reproduce this. Can you post the scene with the textures?

It works now! My background image was about (7000x5000px). I reduced it to 1920x1080 and it works.

So you probably ran out of (GPU) memory?
