Strange effects with Advanced Lighting Model with Linux Firestorm

[Anna Nova]

I've started, in the last two weeks I think, to see very strange effects with the Advanced Lighting Model.  In some regions I get stripes on every surface, and in others I get items flashing on and off as I change my view.   I have not seen anyone else reporting this, and wondered if it was just my set-up.  I am running Firestorm on Archlinux, which is pretty cutting-edge, but I checked with the Official Viewer and got the same effect.  My hardware uses a nVidia GTX 1070ti GPU with a Ryzen 2700x and 32Gb of memory.  All the issues go if I switch ALM off.

Does anyone have any ideas for fixing or researching?

Known issue with the latest Nvidia driver, downgrade until it's patched.

I must be lucky... I think Ubuntu has avoided releasing the latest buggy Nvidia driver in the LTS and 9 month releases. (I use kubuntu LTS with the Ubuntu Studio repos.)

I'm still on Ubuntu 20.04 LTS and am seeing no issues here with the Nvidia driver (v5.10 I believe).

@Jenna Huntsmanwhere did you find that out?  I searched everywhere before I posted here.  And THANK YOU!

I keep an eye on a bunch of SL Discord groups, this issue came up and I remembered when I saw your post!

Ah yep, confirming that 515.48.07 causes banding/artifacting/object flickering.

Stick to 515.43.04 for now.

This kind of thing is the reason why I stay on the LTS releases for Ubuntu.  The whole experience is very stable and support lasts for much longer that the non-LTS releases.  Sure, I miss out on the latest updates to applications but I don't need to be on the latest versions.  Still get all security patches, etc.  Never had my Nvidia driver break either.

Ah, I'm having the same problem as well. My Graphics Card is GTX 1660 Super.

Ya, Arch is a bit cutting edge.  Kernel 5.18.3 and nVidia 515.48.07.  I think Ubuntu would call it 5.15.

Manjaro, Liquorix 5.17.15 here. In this instance it's just the nVidia driver, thankfully.

v5.15 must be for Ubuntu 22.00 which isn't the LTS yet.

It is beginning to look as though NVidia have made a complete hash of their most recent GPU drivers for most Linux and Windows.

Bizzartifacts.

516.40-desktop-win10-win11-64bit-international-dch-whql is a NOPE.  (It doesn't work properly with Second Life.)

So I stepped back to:

512.95-desktop-win10-win11-64bit-international-dch-whql is a YES.  (It works properly with Second Life.)

It's good not to be on the bleeding edge.

I am beginning to believe you....

Just a quick "heads up".  NVidia are now aware of this issue and are apparently "working on it".  I just hope they work quickly.
