Blender crash when using EEVEE renderer

iamtoaster commented 1 month ago

Describe the bug

When trying to switch to material preview mode or rendered mode with EEVEE renderer selected blender crashes.

Steps To Reproduce

Steps to reproduce the behavior:

Open Blender;
In the top-right select "Material Preview" viewport shading mode.

Expected behavior

Different shading mode does not cause a crash

Additional context

I have an nvidia GPU, have this in my config:

nixpkgs.config.cudaSupport = true;

hardware.graphics = {
  enable = true;
  extraPackages = with pkgs; [
    vaapiVdpau
  ];
};

services.xserver.videoDrivers = ["nvidia" "intel"];

hardware.nvidia = {
  modesetting.enable = true;
  powerManagement.enable = false;
  powerManagement.finegrained = false;
  open = false;
  nvidiaSettings = true;
  package = config.boot.kernelPackages.nvidiaPackages.stable;
};

Blender works fine (does not crash upon selection) if Cycles is selected as the renderer and you select Rendered viewport shading.

Here is what is printed into console on crash

While I have a few addons installed, I do not think they are the issue as when I disable all installed addons before switching to material preview blender still crashes ```console [user@computer] [19:53:40] [~] -> % blender HardOps 0.9.88.5 available!

I cannot reproduce on Intel, AMD, or Nvidia GPUs, using Blender 4.2.1.

Does only preview crash, or does rendering also crash?
Try starting with blender --factory-startup (will ignore user config).
Try rebooting if you haven’t since last nixpkgs update to rule out driver mismatch issues.
Blender 4.2.1 will be in the next nixos-unstable update—that may fix; you can wait or try backporting the update to your config.
“Failed to load cached shader binary” seems suspect, but reading the source it deletes the file that failed to load. It might be a symptom rather than a cause, though, or just unrelated.

* Does only preview crash, or does rendering also crash?
Yes, rendering also crashes, but only if EEVEE is selected as the renderer (Cycles works fine)

Try starting with blender --factory-startup (will ignore user config). This... Fixed the issue. Which is rether interesting seeing as my blender config has minimal changes compared to factory one, in fact, it is just the addons I use, CUDA and the statistics on the status bar. Is there a way to run a diff between stock settings and my settings?

I tried disabling all enabled addons, and the crash still happened.

* Try rebooting if you haven’t since last nixpkgs update to rule out driver mismatch issues.

Did not help.

* “Failed to load cached shader binary” seems suspect, but reading the source it deletes the file that failed to load. It might be a symptom rather than a cause, though, or just unrelated.

The crash happens when the UI says in the top left "Compiling EEVEE Engine Shaders"

In conclusion, I think the issue is not with nixpkgs but rather upstream. I will remake my config from scratch, hopefully everything will be fine this time. I will also be closing this issue, thank you for the help.

NixOS / nixpkgs
