I have the exact same issue. 5070 Ti on Fedora, arch and mint, driver 580, same visual artifacts.

This happens to me too with my Pico 4 (non-Ultra version).

GPU: Nvidia 5070 Ti
Driver Version: 580.95.05
CPU: Ryzen 7 5700x
OS: Fedora 42 Workstation
Desktop: Gnome
Windowing System: Wayland

Same issue:

SteamVR beta 2.13.6

Meta Quest 3

OS: Arch Linux x86_64
Kernel: Linux 6.17.7-arch1-1
DE: KDE Plasma 6.5.2
WM: KWin (Wayland)
CPU: AMD Ryzen 9 9950X3D (32) @ 5.76 GHz
GPU: NVIDIA GeForce RTX 5090

Computer connected with wire.
Headset with wifi6

Same issue:

SteamVR 2.14.3

Pico 4

OS: CachyOS x86_64
Kernel: Linux 6.17.9-2-cachyos
DE: KDE Plasma 6.5.3
WM: KWin (Wayland)
CPU: AMD Ryzen 7 9800X3D (16) @ 5.27 GHz
GPU: NVIDIA GeForce RTX 5080, Driver Version: 580.105.08

SteamVR works with ALVR

I tried it now on my notebook too:

CPU: Intel i7-8750H
GPU: iGPU + GTX 1050 Ti Mobile
RAM: 16GB

I have on my PC and the Notebook Arch Linux installed now. Both are running the nvidia-open-dkms drivers.

On my notebook, SteamVR works and I get a picture (it is using the dedicated GPU). On my PC even after switching from Manjaro to CachyOS and now to Arch I still get the same issue.

I then moved the steam folder so steam rebuilds itself again, still the laser disco going on - but only on PC.

That way I just can't pin-point what might cause this issue now. First I thought it was just NVidia, but on notebook it works. Then I thought it's because of dkms (I had the nvidia-open driver prior installed on the PC) but that also didn't changed anything.

But seeing the others here that have a RTX50 series GPU it might be an issue with that? Maybe with nvenc? If someone else is coming over this thread and has a RTX50 series GPU for whom it works, it would be great saying so! Just so we can clarify if it's per user/system or if it might be an issue with the RTX50 series.

Yeah, i've only found people with RTX50 series having this issue. I think that should be looked in to.

Another update:

I am quite certain it's the RTX 50 series that is borked with this. I just tested it with my prior GPU (RTX 4060) and with that one SteamVR (current beta 2.14.3) works without any issues.

The question is now: Is this an issue with SteamVR or something NVidia has to fix?

Edit:
I made a topic on the NVidia forums too as reference

Anyone tried it with the latest 590.44.01 driver? I emailed nvidia directly and they asked me to try this driver, but i cant get it working on my system.

@toastloaf Hey thanks for the info. I just tried with the beta drivers and it works perfectly!

OS: Arch Linux x86_64
Kernel: Linux 6.17.9-arch1-1
DE: KDE Plasma 6.5.3
WM: KWin (Wayland)
CPU: AMD Ryzen 9 9950X3D (32) @ 5.76 GHz
GPU 2: NVIDIA GeForce RTX 5090 [Discrete]
Driver Version: 590.44.01

Can also confirm: the beta driver works now!
