HoloLens Depth Buffer errors

Hey guys,

Getting an error on the HoloLens
"Failed to commit the depth buffer via CommitDirect3D11DepthBuffer. Error Code '0x80070057'"
(Filename: C:\buildslave\unity\build\Runtime/VR/HoloLens/VRDeviceHoloLens.cpp Line: 560)

Only happens occasionally (once out of ten launches)
Anyone have a clue what it's related to?

HoloLens OS: 10.0.17133.1009
Win SDK 10.0.17125.0
Unity 2017.4.0f1

Build Settings:
D3D
.NET Scripting Backend using 4.x
Enabled Shared Depth buffer in Windows MR SDK

 

I didn't open a bug report, cause every time I do, Unity doesn't honor it because I'm using the RS4 Insider Preview.

 

Just hit this on Unity 2017.4.4f1 as well...

 

Yep... easiest steps I think are:

New Project,
Switch platform to UWP
Enable Depth buffer in Player Settings > Windows Holographic MR settings
Launch Holographic Remoting app on an RS4 HoloLens
Use Holographic remoting to connect to the remoting app and then hit Play
Notice the tons of errors in the Unity Editor Console that say:
Failed to get rendering parameters for main camera - view transforms may get out of sync! Error code: '0x80004002'

Other method:
Do all of the above, but compile into an actual app and deploy onto the hololens
Attach the debugger and notice the error in the output window that say:
Failed to commit the depth buffer via CommitDirect3D11DepthBuffer. Error Code '0x80070057

Unity 2017.4.4f4
Host OS Windows 10 16299.431
HoloLens OS Windows 10 17134.80

Note:
I think the depth buffers might be getting sent over some of the time. The whole point of sending the depth buffers is so that the focus point is automagically picked by the HoloLens and I can see that the stabilizationplane is in fact being set automatically when I visualize it in 3DView and get closer or further away from an object.

 

I don't think this is an issue with RS4. I have a hololens running 14393.2248 (Anniversary Update) that also has the issue when shared depth buffer is enabled for both 16- and 24-bit depth buffers.

I am using:
Unity 2017.4.2
Visual Studio 2017: 15.7.3
Windows OS: 10.017134.0
Holo OS: 10.0.14393.2248 (RS1)

If I disable shared depth buffer, I stop seeing the errors. Unfortunately, I cannot share my project source code, but please PM me if additional information is needed.

 

I'm running into this issue with the shared depth buffers with the following setup:

Unity 2018.3b9
HoloLens OS: 17134.228.x86fre.rs4_release_svc_prod1.180802-1721

Same symptoms - around 1 out of 10 launches doesn't render anything while the debug console spews:

 

Hi,
I'm running occasionally into this issue also with my app available for HMD (the app is made with Unity 2017.4.11f1)
I am unable to reproduce the problem on my machine.
Below are all the information I have available (I am tracing my app with App Center)

Errors:
Failed to update back buffer on holographic camera - renders may become out of sync! Error code: '0x8000000e'
Failed to get rendering parameters for main camera - view transforms may get out of sync! Error code: '0x80070102'
Failed to update back buffer on holographic camera - renders may become out of sync! Error code: '0x80070102'
