YF: Yes, it might be the same problem. It looks like there is a limit on amount of pixels or something, and it affects not just headless mode.

I also have this problem with a very large html-file. I try to take a screenshot, the tool seems to hang and then I receive an error:
Here is a copy from the developer console:
Error: Promised response from onMessage listener went out of scope ExtensionMessagingService.js:89:34

The only screenshot-tool, which works for my large html-page is FireShot.
Problem: I can reproduce this problem only with my large html-page, which contains sensitive information of my company, so I can't post it.
Further tests:

  • CSS is not the problem: I removed all CSS, and the problem still occurs.
  • It does not happen if I replace all images with the same image.
  • It does not happen on other pages with much more images.
