Bumps wgpu from 25.0.2 to 30.0.1.

Changelog

Sourced from wgpu's changelog.

v30.0.1 (2026-08-21)

Bug Fixes

Vulkan

• Stop passing an un-waited fence to vkAcquireNextImageKHR on non-Windows platforms, which triggered VUID-vkAcquireNextImageKHR-fence-10066 validation errors every frame since v30.0.0. By @​ErichDonGubler in #9855.

Metal

• Resolve metal color space constants dynamically. By @​andyleiserson in #9819.

WebGPU

• Upgrade vendored WebGPU bindings and wasm-bindgen to 0.2.127. This fixes a panic “can't access property "info", arg0 is null” when using the WebGPU backend and requestAdapter() fails. By @​beicause in #10034, backported in #10105.

v30.0.0 (2026-07-01)

Major changes

Optional vertex buffer slots

This allows gaps in VertexState's buffers and adds support for unbinding vertex buffers, bringing us in compliance with the WebGPU spec. As a result of this, VertexState's buffers field now has type of &[Option<VertexBufferLayout>]. To migrate, wrap vertex buffer layouts in Some:

  let vertex_state = wgpu::VertexState {
      module: &vs_module,
      entry_point: Some("vs_main"),
      compilation_options: wgpu::PipelineCompilationOptions::default(),
      buffers: &[
-         &vertex_buffer_layout
+         Some(&vertex_buffer_layout)
      ],
  };

By @​teoxoy in #9351.

Integer shader I/O no longer defaults to @interpolate(flat)

To align with the shading language specifications, naga no longer assumes that integer-typed shader I/O should have flat interpolation, i.e., should not be interpolated. Even though flat interpolation is the only choice for integer I/O, it must be still specified explicitly.

WGSL:

 struct FragmentInput {
     @location(0) tex_coord: vec2<f32>,
-    @location(1) index: i32,
+    @location(1) @interpolate(flat) index: i32,
 }
</tr></table>
