DevTools Page.captureScreenshot endpoint is inconsistent (fails > 50%)

The above should reproduce, as of nightly and stable

/*
const process = require('process');
process.env.DEBUG = 'puppeteer:*';
process.env.DEBUG_COLORS = '1';
*/

const path = require('path');
const fs = require('fs').promises;

const sleep = require('await-sleep');
const puppeteer = require('puppeteer-core');

(async () => {
  console.log('Launching browser...');
  const browser = await puppeteer.launch({
    executablePath: '/usr/bin/brave-browser-nightly',
    args: [
      /*
      '--enable-logging=stderr',
      '--v=1',
      */
      '--disable-brave-update'
    ],
    /*
    dumpio: true,
    */
    headless: false
  });

  console.log('Opening new tab...');
  const page = await browser.newPage();

  console.log('Navigating to page...');
  await page.goto('https://smartads.lt/');

  console.log('Waiting...');
  await sleep(1000 * 15);

  console.log('Taking screenshot...');
  const screenshot = await page.screenshot();

  console.log('Saving screenshot...');
  await fs.writeFile('screenshot.png', screenshot);

  console.log('Done')
})();

Does this need QA? Sounds like screenshots aren't working in certain cases?

This is only when going through puppeteer (or other programatic devtools interfaces). This is distinct from user facing screenshot tools in the devtools UI (if they exist, im not sure).

And not certain cases, seems totally intermittent

Q/A would be great, but would need someone with at least some development skills, since youd need puppeteer and (a little) node experience to reproduce
