wgpu: DX12 Assertion failed left: -2005270523 with read only buffer

Description: I have a storage buffer that contains all the matrix data. Every object in my game has an offset for it’s data in this buffer.

My shader looks like this: layout(set=2, binding=0). readonly buffer StorageBuffer{ mat4 transform;. }; (This is only a small snippet for the relevant part.)

I am creating the buffer like this: let buffer = device.create_buffer(&BufferDescriptor { label: None, size: BIND_BUFFER_ALIGNMENT * 100, usage: BufferUsage::STORAGE | BufferUsage::COPY_DST, mapped_at_creation: false });

Here is the code bindgroup: device.create_bind_group_layout(&BindGroupLayoutDescriptor { label: None, entries: &[BindGroupLayoutEntry { binding: 0, visibility: ShaderStage::VERTEX, ty: BindingType::Buffer { ty: BufferBindingType::Storage { read_only: true },has_dynamic_offset: true, min_binding_size: BufferSize::new(64) }, count: None }] })

In the render pass I am using it like this: render_pass.set_bind_group(2,&camera.transform_bind_group,&[offset]);

If I change the storage buffer to a uniform buffer (in the shader too) everything is working.

The thing is this is all working perfectly fine on the VULKAN backend (with the storage buffer). I only wanted to test DX12 out and then I noticed this bug.

Extra materials: panic: thread 'main' panicked at 'assertion failed: (left == right) left:-2005270523, right: 0: error on command list creation: 887a0005'

Repro steps Use the DX12 backend. Use a SSBO in a shader.

Expected vs observed behavior panic vs no panic No panic on DX12 and VULKAN vs panic on DX12
