Scanlines Visible with multi GPU + Fur

[anthony_billet]

We're experiencing a similar banding issue using two RTX 6000 Ada cards on our workstations. We're not using fur in our scenes, but we are using ForestPack, though the issue seems to be across the full scene rather than isolated to a specific object. I'm currently resorting to disabling a card to get clean results, but it would be great if there's an alternative solution that doesn't involve waiting for a patch.

Edit: Well disabling was a wash, it seems like I'm still getting the lines even rendering on a single card, any ideas as to what's causing it? It's particularly noticeable in clouds.

Can you send the scene to support so we can debug it ?

Sure thing, I'll archive the file tonight and get it over first thing in the morning along with the most recent Vantage config I've tried.

anthony_billet which denoiser are you using?

the issue seems to be across the full scene

The screenshot only shows clouds. Does it happen with actual geometry? Can you show an example other than clouds?

We've reproduced this and are preparing a fix. Just to clarify: it has nothing to do with the fur issue or multiple GPUs.
