Maximum dynamic offset limit is incorrect per the spec

6

If I'm reading this right, according to the [spec](https://www.w3.org/TR/webgpu/#gpubindingcommandsmixin-setbindgroup), the requirement for the dynamic offset for a buffer binding is that `bufferBinding.offset + dynamicOffset ≤ bufferBinding.binding.size - bufferLayout.minBindingSize`. That is,...

Question: Are texture samples specified to be taken at a corner or center?

9

When calling, e.g., `textureSampleGrad(tex, sampler, st, dst_dx, dst_dy)`, is the effective sampled area of the texture a patch with "origin" at `st`, e.g. `st + J * xy`, with `xy`...

Question: Is sharing of native textures / buffers supported?

1

Apologies if this is available and I missed some documentation—  Is it possible to "import" or "export" a native (i.e., Vulkan, Metal, etc.) texture or buffer into wgpu? I see...

Many frames of latency between input and render

3

### Summary Zed shows multiple frames of latency (I count at least four) between input and render. See the attached video for an example: https://github.com/user-attachments/assets/09cae02e-3bdf-4f85-9090-2cfc9981a5f0 ## Steps to trigger the...

Glfw platform macros not set

1

I had some trouble with `glfwCreateWindowWGPUSurface()` returning `nullptr`, and after debugging found that the internal switch was falling through to [L178 in glfw3webgpu.c](https://github.com/eliemichel/glfw3webgpu/blob/main/glfw3webgpu.c#L178) because none of the platform macros had...
