1903102 - Change usage of WebGPU to use vertex pulling transform (only meaningful for macOS/Metal) all the time

Status: RESOLVED FIXED

(Core :: Graphics: WebGPU, defect)

Description

[Brad Werth [:bradwerth] | Out until March 3]

macOS WebGPU has been disabled by default in part because of concerns about out of bounds indexes in indirect draw calls. wgpu was updated to add a vertex pulling transform (only respected for macOS/Metal). The feature is gated behind a flag that we currently set to false. Set that flag to true and confirm that our test results are no worse than they were before. Eventually the flag will be removed and we'll have to change this again.

One issue already revealed. This will require wgpu revendoring after fixup https://github.com/gfx-rs/wgpu/pull/5829 lands.
