But it compiles on linux/chrome, android/chrome. Error message also strange, override keyword not present in wgsl source: ===== const PTK_HASHDATA = array<array<u32, 16>, 1>(array<u32, 16>(0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0)); const EAPOL_HASHDATA = array<array<u32, 16>, 1>(array<u32, 16>(0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0)); @group(0) @binding(0) var<storage, read> input: array<u32>; @group(0) @binding(1) var<storage, read_write> output: array<u32>; @compute @workgroup_size(64) fn main(@builtin(global_invocation_id) gid: vec3<u32>) { output[gid.x] = gid.x; } ===== Quick check: https://georg95.github.io/wgsl-safari-bug.html 2160104 1 georgsh-yateam 2025-11-19 17:36:17 -0800 So, actually issue is you can't declare 2-d const arrays. Can change to const to var<private>, but probably with performance penalty 2160105 2 webkit-bug-importer 2025-11-19 17:46:26 -0800 <rdar://problem/165093959> 2173255 3 tzagallo 2026-01-20 01:59:54 -0800 Pull request: https://github.com/WebKit/WebKit/pull/56885 2174128 4 ews-feeder 2026-01-22 09:31:04 -0800 Committed 306020@main (4f07563c85a8): <https://commits.webkit.org/306020@main> Reviewed commits have been landed.
