DX12 & OpenXR consistent crashing.

Freakish · July 31, 2021, 4:46am

I’m having a few crashes that are driving me crazy, wondering if this gives any insight to anyone, as to what is failing and where. Or where I should be looking for more info?

It appears to be OpenXR and DX12 related. I have forced DX12 Debug from the commandline: It has shown a bit more info, but beyond my depth.

Any help would be appreciated.

Hi @Freakish ,

Could you please submit a bug report for this issue so we can have a look at your log files?

Freakish · August 7, 2021, 9:34am

I started a clean DX12, OpenXR project today and just submitted the crash (Case 1356281) from that.

I did notice this time that it crashed 3 out of 4 times, if I clicked from the ‘Game’ Tab to the ‘Scene’ Tab during play mode.

But it happens seemingly randomly otherwise. For example I have successfully setup and used multiple Grabbable items, teleport and snapturning, and tested them two dozen times without a single crash… Just now had it work 6 times, and on the 7th time I pressed play, crash.

Thanks a lot for taking a look, would appreciate any help.

@Freakish What I found in past was that:

OpenXR works in DX11 without issues
OpenXR works in DX12 while using Oculus runtime (Depth Submission Mode can be set to any value and it will work)
OpenXR crashes in DX12 while using OpenVR/SteamVR runtime with Depth Submission Mode set to anything but None

So first thing I’d test on your case is making sure Depth Submission Mode is set to “None”. Not sure if you need this mode enabled for anything but things like Oculus ASW.

Freakish · August 8, 2021, 3:53am

Thanks rz_0lento.

I never got any image displayed in the HMD (Oculus Q2 headset) when using any Depth Submission Mode set to anything other than none, I didn’t get crashes, when set to anything else, but couldn’t get an image in the Oculus HMD.

So the crashes I’m experiencing do have the depth submission mode set to none.

[LIST=1]
[*][XR] [31636] [14:31:49.897][Info   ] Depth Submission Mode: None']

[/LIST]

But thanks for the suggestions nonetheless. I will however perhaps try to see if I have less issues using the Oculus Runtime, and not the SteamVR which has been my standard for sometime now, to see if I can get more mileage that way.

I have a similar issue here.

I am running a HDRP + VR + OpenXR project.

I need to render a few pictures with the path tracing feature for marketing purposes (will be deactivated in the build or in play mode, I don’t need any RT features) but at the very moment I enable DX12 Unity crashes almost instantaneously, sometimes after a few clicks.

Unity 2022.3.0.1f + openXR + URP + ECS

Just switched a project from a working Dx11 to a randomly crashing Dx12. Has there been any progress on the reported bug?

I’ve bug reported without a sample project (IN-46781), but my editor log seems very similar.
