--- Comment #4 from Mike Wyrzykowski <mwyrzykowski at apple.com> ---
Failing lines are:

131:    return float4(state)/float(0xffffffffu);
300:            var color = spectral_zucconi(400 + 0.2*float(i-512));
312:     let idx0 = int(id.x) + int(screen_size.x * int(id.y));
326:     state = uint4(id.x, id.y, id.z, uint(custom.NoiseAnimation)*time.frame);
328:     for(var i: i32 = 0; i < int(custom.Samples*MaxSamples + 1.0); i++)
341:      let x = float(atomicLoad(&atomic_storage[idx*4+0]));
342:      let y = float(atomicLoad(&atomic_storage[idx*4+1]));
343:      let z = float(atomicLoad(&atomic_storage[idx*4+2]));    
359:      let fragCoord = float2(float(id.x) + .5, float(id.y) + .5);

Its possible some of these are due to Tint being out of compliance with the current WGSL specification, see https://github.com/gpuweb/gpuweb/issues/4415#issuecomment-1850152484
