I'd like to render points with PIXI.DRAW_MODES.POINTS and shaders. But I am not successful in displaying it.

A minimul example is shown below.(https://codepen.io/raycast/pen/eYmvRoW)


const renderer = new PIXI.autoDetectRenderer();
renderer.view.id = 'pixi-canvas';

const geometry = new PIXI.Geometry()
              [100, 100,    // x, y
               100, 200,   // x, y
               300, 200], // x, y

const vertexSrc = `
precision mediump float;

attribute vec2 aVertexPosition;

uniform mat3 translationMatrix;
uniform mat3 projectionMatrix;

void main() {
  gl_Position = vec4((projectionMatrix * translationMatrix * vec3(aVertexPosition, 1.0)).xy, 0.0, 1.0);

const fragmentSrc = `
precision mediump float;

void main() {
  gl_FragColor = vec4(1.0, 1.0, 1.0, 1.0);

const shader = PIXI.Shader.from(vertexSrc, fragmentSrc, null);
const mesh = new PIXI.Mesh(geometry, shader);
mesh.drawMode = PIXI.DRAW_MODES.POINTS;           // doesn't work
// mesh.drawMode = PIXI.DRAW_MODES.TRIANGLES;     // works fine

const stage = new PIXI.Container();

This code in any other PIXI.DRAW_MODE works fine.

WebGL Points exsample(https://codepen.io/duhaime/pen/YaRaNX) works too, 
so I think that the cause of this problem is not my environment.

pixi v5.2.0
Windows10 / Chrome79.0.3945.88

I'd really appreciate it if you could give me your advice.

Honestly, I have no idea what can be wrong here. I used POINTS with pixi before , but not in v5. I traced execution flow, placed breakpoints, and it all looks good.


Spector shows completely normal frame commands:
