sometimes PNG snapshots of unfinished renderings

[axelzuzek]

I generate a sequence of ~10000 PNG-images for an animated video using

 Browsershot::html($html)
  ->setScreenshotType('png')
  ->hideBackground()
  ->windowSize(2160, 2160)
  ->fit(Manipulations::FIT_CONTAIN, 2160, 2160)
  ->save($file);

about 1% of the images shows unfinished renderings of the html page, sometimes single groups of text or symbols are not rendered, sometimes no text is rendered at all, in rare cases svg elements are missing too. After starting the renderings of those faulty images again the problem is not reproduceable. I checked the source $html for those faulty cases, it is always 100% ok and rendered in chrome without any problems.

"spatie/browsershot": "^3.52",

adding

  ->waitUntilNetworkIdle()
  ->setDelay(500)

solved the problem.
