Editor Crash - Createdirect3d11surfacefromdxgisurface

Unity Engine
1

Hi everyone,

I’ve been running into an issue fairly consistently: In one of my scenes the editor crashes as soon as I start orbiting (alt + left click) the camera.
Zooming in/out does not seem to cause a crash, neither does changing the FOV.

EDIT: It turns out the crash only happens when the scene view is focused.

This happens in 2018.2, 2018.3 and 2019.1b10.

I tried submitting a bug report, but the error reporting from crashed saying it failed to read a file.
I’m happy to provide dmp files and anything else to someone at Unity.

Thanks!

Does it also fail if you just open this project in the editor and click “Help > Report a bug…”?

Alternatively, you could submit a bug-report with all the required information, but without the project itself, and ask Unity QA to provide a safe owncloud location, where you can upload your project (as .zip archive for example) afterwards.

If either of these options work for you, then please submit a bug-report as described in this document:

It’s important that you report these issues together with a reproduction project if you want them to get fixed. If you don’t do it, it might be a long time until someone else reports them or until Unity Technologies find them.

After you submitted the bug-report, you receive a confirmation email with a bug-report Case number. You can post the Case number (number only, not the link) in this forum thread for Unity staff to pick up, in case they see it.

After upgrading to 2019.1.0f1 I managed to submit a bug report: Case 1146327

Do you call Shader.WarmupAllShaders()? In my case this was the problem and traces showed the same API failure: CreateDirect3D11SurfaceFromDXGISurface in D3D11.DLL.
