Bug Unity editor crashes frequently on Linux+Vulkan after updating GPU drivers

After updating my GPU drivers today, the Unity editor crashes very frequently - sometimes right as soon as it opens, sometimes after switching layouts, and every time if trying to open a window such as the project settings.

My system and Unity setup is as follows:

• OS: Fedora Silverblue 39, GNOME 45, Wayland (though issue occurs on X11 as well)
• GPU: Nvidia RTX 3090Ti with proprietary drivers version 550.54.14
• Unity Hub through Flatpak, Unity Pro license activated
  
• Editor using Vulkan
  
• Editor versions 2022.3.0f1 and 2022.3.20f1 have both been tested with the same issue

At the end of this post, I have included the output I get when running the editor in a terminal with `-LogFile` right as it crashes. There are no relevant lines before this segment, but if there's a way to enable more verbose logging I'd happily do so!

I have also tried creating a new, empty project, and the issue occurs there as well. It does _not_ seem to crash - or at least not as often - under OpenGL, but for unrelated reasons that is not an option in my case.

Does anyone have any thoughts as to what initial steps to troubleshoot this might be?

My dev team also experience this issue on Arch Linux (yes, it's not officially supported).
For now had to downgrade packages to previous nvidia driver.

 

Thanks for confirming this is not an isolated issue! Indeed rolling back the drivers does work, or simply switching to OpenGL temporarily. From what I've seen this might be fixed in an upcoming Vulkan SDK update, so hoping it will be resolved soon!

 

Same issue here (also on Arch), but I get the crash regardless of whether I'm using OpenGL or Vulkan.
However, rolling back the nvidia drivers to 545.29.06 fixed it for me for now as well.

 

I've got the same issue as well. My project uses Vulkan. Switching to 545 fixes it.

 

Also experiencing this on arch, haven't tried rolling back yet but this sounds like the exact same problem im having.

 

Same on Manjaro, holding back any system updates until this is resolved. Are we sure this is for nvidia to fix and not unity? I guess its a driver issue, but you never know

 

Can confirm this issue remains on driver version 550.67. Still can't pin down why it seems to sometimes work and sometimes not - at times it doesn't happen for an hour or two, then is back to happening all the time.

 

Can confirm this problem randomly started occurring while using 2023.2.6f1, and no i did not upgrade or change my display driver during this time. It crashes on opening.

I will note:
1. I extracted a new copy of unity and the crash occurs on new or existing projects.
2. I am on ubuntu mantic.
3. It was working a few days ago just fine.

Drivers:

| NVIDIA-SMI 550.54.14 Driver Version: 550.54.14 CUDA Version: 12.4

 

Has someone perhaps already reported this as a Unity bug using the in-editor reporting tool?

Might take some time for them to look at it, but I don't know if a lot of devs look at the forums for issues like these.

 

Same, but strangely not on every project. Driver version: 550.67

 

Nice, downgrading the Nvidia driver from 550 to 545 worked for me as well.

Do you mind testing to run your project on 550 with `-force-vulkan-layers`?
In my case, the destruction of an invalid VkImage was attempted during swapchain recreation...

 

Had the same problem on EndeavourOS + driver 550.78 on both Wayland and X11 and downgrading to 545 fixed the issue.

One thing for EndeavourOS users is that you also need to downgrade the kernel. I had to go up to 5.15.

 

Tried adding this on 550.40.61 (RTX 3060 on EndeavourOS with Linux kernel 6.9.2-arch1-1, Unity 2022.3.30f1), and surprisingly enough it works! Had some issues downgrading to 545, so tried using `-force-vulkan-layers`, and it works on 550.

Edit: Some windows still manage to crash unity such as the ProBuilder window, but it's far more stable than it was before adding this.

 

I think this may be this upstream bug issue.

 

+1 this appears to have solved my issue as well, on Fedora 40.

 

I'm experiencing this. Pop_OS 22.04, 550.67. The `-force-vulkan-layers` flag doesn't seem to do anything.

Once per boot, I can open my project in OpenGL, then switch to Vulkan within the Editor. That tends to work, but only once per boot

If I close the project, it won't open under Vulkan again, and after a reboot, it still won't open. I have to edit the project settings to revert it back to OpenGL.

So my currently 'workflow' is:
- ensure project settings is set to OpenGL
- restart PC
- start the project (in OpenGL)
- switch to Vulkan in editor

Tends to work, but boy is it making sad.
