Thank you for the repro! Very helpful :)

I made a more minimal repro case:

import type { PlaywrightTestConfig } from '@playwright/test';

const config: PlaywrightTestConfig = {
  testDir: './tests',
  reporter: [
    ['html', { open: 'never', outputFolder: './report' }],
    ['list'],
  ],
  use: {
    trace: 'on',
    video: 'on'
  },
  projects: [
    {
      name: 'Firefox',
      use: {
        browserName: 'firefox'
      },
    },
  ],
};

export default config;

import { test } from '@playwright/test';

test('Inventory Page - Navigate', async ({ page }) => {
    await page.goto('https://example.com');
    await page.waitForTimeout(2000);
})

-> when trace and video is enabled, Firefox ends up in a white video.

A partner team is onboarding to Playwright 1.19, I recommended to use: { "trace": "retain-on-failure", "video": "retain-on-failure", } but strangely they only get traces. No video at all.

Any update on this? It is still happening in version 1.22.1

[AdiRishi]

This is still present in playwright 1.25.2. Any updates?

We're seeing this error on playwright 1.27.1.
