Full page screenshot issue in headful mode

Steps to reproduce

Tell us about your environment:

• Puppeteer version:1.17.0
• Platform / OS version: Ubuntu 18.04.1 LTS and OSx 10.14
• URLs:
  • https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md
  • https://pastebin.com/XcHLqyNC
• Node.js version: 8.15

What steps will reproduce the problem?

Run this code

const puppeteer = require("puppeteer");

(async () => {
  const browser = await puppeteer.launch({ headless: false });
  const page = await browser.newPage();
  await page.setViewport({
    width: 1920,
    height: 1080
  });

  await page.goto(
    "https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md",
    {
      waitUntil: "networkidle0",
      timeout: 0
    }
  );

  await page.screenshot({
    path: "check-this-screenshot.png",
    fullPage: true
  });

  await browser.close();
})();

What is the expected result? One should get a full page screenshot in both the scenario:

1. headless: true
2. headless: false

What happens instead?

1. headless: true: getting the correct full page screenshot
2. headless: false: getting the blank screenshot/No screenshot

Looks like we’re hitting GPU limit on headful easily. Chrome DevTools limit max content height to 2^14 - we should probably do this as well.

@aslushnikov any update on this?
