Firefox

Operating system

MacOS

Steps to reproduce this

Steps:

1. In buildGeometry, draw a shape with per-vertex stroke colors
2. Draw the geometry
3. The stroke colors do not show up

The stroke vertex colors property of the geometry is an empty array, so it seems it's not getting created. Not sure if this is related or just a documentation/FES bug, but it also logs this message:

Expected number at the first parameter, but received null in color().

Snippet:

let geom

function setup() {
  createCanvas(400, 400, WEBGL);
  angleMode(DEGREES)
  
  strokeWeight(5)
  noFill()
  randomSeed(5)
  geom = buildGeometry(() => {
    // *** remove/replace POINTS and works as expected
    beginShape(LINES) // LINES or TRIANGLES or empty works fine
    for(let i=0; i < 50; i++){
      //push()
      stroke(random(255), random(255), random(255))
      let x = random(-width/2, width/2)
      let y = random(-width/2, width/2)
      let z = random(-width/2, width/2)
      vertex(x, y, z)
      vertex(x, y, z+10)
      //pop()
    }
    endShape()
  })
}

function draw() {
  background(0);
  orbitControl(3)
  rotateY(frameCount/3)
  
  strokeWeight(5)
  // stroke(255) // uncomment to show points
  model(geom)
}

Run the provided p5.js sketch in Firefox and inspect the WebGL paths used by buildGeometry and model, focusing on how POINTS captures per-vertex stroke colors. Done means the geometry retains those colors and model(geom) renders the expected strokes without the reported color() warning.
