Crash when instantiating SpoutReceiver on standalone DX12 build, Unity 2021.2.0.13b, GTX1660 SUPER

[WoutStandaert]

I have a standalone Unity build running on a GTX1660 SUPER.

At a certain moment I try to instantiate a prefab with a SpoutReceiver on it.

The SpoutReceiver renders to a render texture, the "renderer" field is not set.

The render texture is displayed via a RawImage on a UI canvas.

During development, it works in the editor on my laptop with a RTX 2060.

In the build on a GTX1660 SUPER, it crashes with the following error:

d3d12 : CreateCommittedResource 'TexturesD3D12::CreateTextureInternal() Texture' (1920 x 1080) format 72 failed (887a0005).

Crash!!!

Does it reproduce with the sample project (the project contained in this repository)?

[WoutStandaert]

The sample project also crashes.

I did the following:

• Downloaded the repository
• Opened the project with Unity 2021.2.0.13b, which upgraded some things
• Switched the render API from directx11 to directx12
• Made a build of the "Test" scene

The reason why it crashes is different, but it also seems to be related to DirectX 12 memory management:

Device removed reason (887a0001).

Crash!!!

I'm not bound to DirectX12 for my project. I might go back to DirectX11 for now. I've read that one of the big differences between DX11 and DX12 is memory management, so the source of my problem might very well lie there.

The standalone version of my application also crashes on my RTX2060 powered laptop. In the Unity editor it works.

Thanks for the clarification.

I only found very few similar cases. Unfortunately, the root cause of the problem is unknown. Sometimes it disappears by upgrading the graphics driver.

I'd recommend switching to DX11 if it reproduces with the latest driver.

[WoutStandaert]

Switching to DX11 fixes the problem. Thanks for looking into it!

I'm closing this issue. Although the issue still exists, there is nothing to do on my side at the moment. I'll reopen it when I get more information about it.
