Assert failed in Dx12 backend during queue_write_buffer

[Imberflur]

Description
I received a report that an assert failed during this call.

Repro steps
checkout imbris/wgpu-master-rebased from https://gitlab.com/veloren/veloren and run in Dx12 backend (WGPU_BACKEND=Dx12) (I have not reproduced this myself. I suspect it is specific to the GPU/driver)

Expected vs observed behavior
no panic vs panic

Extra materials

• Panic:

PanicInfo: panicked at 'assertion failed: `(left == right)`
  left: `0`,
 right: `-2005270523`', C:\Users\D\.cargo\git\checkouts\gfx-e86e7f3ebdbc4218\2a93d52\src\backend\dx12\src\device.rs:2438:9

I think this corresponds to 0x887A0005 or DXGI_ERROR_DEVICE_REMOVED
the call to CreatePlacedResource appears to fail: https://github.com/gfx-rs/gfx/blob/2a93d52661aafcbd6441ea83e739c8ced906cd21/src/backend/dx12/src/device.rs#L2440

Another way you could help is running this from Visual Studio and seeing what the validation layer thinks about this error.
Edit: ah, ok, nothing interesting by the validation then

So this error message from VS doesn't really give us any useful information?

[kvark]

That's an unfortunate thing. The error basically means a GPU crash, the conditions for which weren't caught by DX runtime validation. Note that this is DX11.1 class hardware, and it's always been a little tricky. We fully intent to ship on it though, so we want this solved.
I'll try to see if we can submit a bug somewhere for Intel or Microsoft to have a look.

(fwiw, the trace works fine on a modern GPU)

[kvark]

Could you please use the helper tool to get information about the system/driver versions? I'm going to submit a bug there, unless you want to.
Note: we'd want to provide a repro case based on the API trace, not the whole veloren.

Thank you! Filed as IGCIT/Intel-GPU-Community-Issue-Tracker-IGCIT#44

Closing as stale due to hal rewrite, please refile if it's still an issue.

👍 Whenever we update we will see if any users still report this.
