Cannot copy 3D texture data

[almarklein]

In the latest release, I am having trouble getting some of our tests at wgpu-py to work. In particular, everything related to 3D textures fails. Some (incomplete) Python code to illustrate the problem:

        size = 64
        
        buffer = device.create_buffer_with_data(data=<64x64x64x4 bytes array>)

        texture = device.create_texture(
            size=(size, size, size),
            dimension=wgpu.TextureDimension.d3,
            format=wgpu.TextureFormat.rgba8uint,
            usage=wgpu.TextureUsage.TEXTURE_BINDING | wgpu.TextureUsage.COPY_DST,
        )

        command_encoder.copy_buffer_to_texture(
            {
                "buffer": buffer,
                "offset": 0,
                "bytes_per_row": 4 * size,
                "rows_per_image": size,
            },
            {"texture": texture, "mip_level": 0, "origin": (0, 0, 0)},
            (size, size, size),
        )

I get :

thread '<unnamed>' panicked at 'Unable to copy buffer to texture:
Transfer(BufferOverrun { start_offset: 0, end_offset: 4145152, buffer_size: 1048576, side: Source })',
src/command.rs:167:6

The buffer_size is correct (1048576 == 64*64*64*4), but that end_offset does not seem to make any sense ...

From skimming through the wgpu-core's commit history, there have been some changes related to the validation of data transfers. Am I missing something or could it be that it is broken (in wgpu-core 0.14.2)?

Found it. It's a bug here in wgpu-native.
