Full page screenshot looks ok, but the timeline view has incorrect dimensions:

Edit: current workaround for Puppeteer is to use ignoreDefaultArgs: ['--enable-automation']

await puppeteer.launch({
  ignoreDefaultArgs: ['--enable-automation'],
});

Edit2: The above workaround isn't enough if you are using Chrome for testing which Puppeteer uses by default now. You can specify a path to a normal Chrome executable as a workaround:

await puppeteer.launch({
  ignoreDefaultArgs: ['--enable-automation'],
  executablePath: '/path/to/chrome'
});
