Question Unity Player Crash after some time - error 0x887a0005

Hi,
I encountered a crash on my windows builds. Unfortunately, this crash only happens after some time and is not consistently reproducible. We run this application on 15 machines (same hardware config) and get at least 2-5 crashes in 4 hours. I attached a crash dump and logs.

The player log looks very normal until it ends with this:

D3D11: Failed to create RenderTexture (1920 x 1080 fmt 27 aa 1), error 0x887a0005 

(Filename:  Line: 207)

D3D11: Failed to create RenderTexture (1920 x 1080 fmt 19 aa 1), error 0x887a0005 

(Filename:  Line: 207)

Crash!!!

I checked the error code 0x877a0005 and it maps to DXGI_ERROR_DEVICE_REMOVED. The graphics card in all these is Intel UHD Graphics 630 so physically removing the graphics card is not possible. Here is some info on that:

Direct3D:

    Version:  Direct3D 11.0 [level 11.1]

    Renderer: Intel(R) UHD Graphics 630 (ID=0x3e91)

    Vendor:   

    VRAM:     3982 MB

    Driver:   26.20.100.7323

Any help / hint / solution is appreciated.

Best regards,
Josh

 

I saw this for the first time as well, Unity 2019.3.15f1

Hello @Josh_He , we have an identical problem on 20 or so devices similar to yours (Intel NUC7i5, Intel UHD 640 graphics).

Since your post, have you been in touch with the Unity QA team to get this resolved?

 

Hey, we tried to replicate the issue on some devices used for testing during development and weren't able to get the same crash. The actual devices are not connected to the internet so they never updated any drivers and that's what we did to resolve the error.
However I can't yet fully confirm it doesn't happen anymore. Because of the pandemic the exhibition (museum) is closed and the application is not used at the moment.

So my best advice is double check the (graphics-)drivers since we have not seen the crash after that.

Best regards,
Josh

 

Hello Josh,

We're indeed looking into driver issues (latest and older ones), but can't seem to find consistency in the behaviour using either.

Thanks a lot for the swift reply, we'll keep on looking!

kind regards,
Davy

 

Any luck guys? Having the same issue.

 

Hi Joe, we had better results using OpenGLCore (OpenGL 4.5) instead of DirectX on these particular devices.

 

We figured out our issue. It came from an infinite loop inside of a Shader, specifically from the asset Volumetric Lights (Kronnect). The dev was extremely helpful and we managed to fix the issue.

 

Thanks!!
Really helped with: Intel(R) UHD Graphics 640

 

@Tautvydas-Zilys. We are also facing the same issue with the standalone windows build using Unity 2019.4.30 LTS version. The build is getting after some time not at all places, but on some places. Same Crash with below message:

"D3D11: Failed to create RenderTexture (1920 x 1080 fmt 27 aa 1), error 0x887a0005
(Filename: Line: 207)

D3D11: Failed to create RenderTexture (1920 x 1080 fmt 19 aa 1), error 0x887a0005
"

Any help on this would be great. Also, I have one concern regarding Graphics API. If we make windows standalone build with using OpenGLCore API only, will it improve the performance?

 

I got the same problem right now. can you help me ? my unity version is 2021.3.25f1 LTS version

 

I got it also

 

Hello, We have same problem too. (2022.3.3f1 LTS)
