I can't reproduce with the URLs listed above on Chrome stable 65.0.3315.0, running on Windows 10 1607 with nVidia Quadro K2000. Can anyone else reproduce?

We are able to see the web pages clearly with out any diagonal lines. Attaching the screen cast of the same.

@Reporter: Could you please check the screen cast and let us know if we have missed any steps. Please check the same in a fresh/new profile and let us know if the issue still persists.

Thanks!

Yep, you've followed the steps correctly.

I have attached a screencast of my own.

Both my friend and a QA person from Travis CI was able to reproduce it. While I don't think it's relevant, I have also attached the email to Travis support.

I managed to run chrome with `chrome.exe --user-data-dir="D:/emptyDir"`

The end result is fascinating. The initial run it appears, and then disappears as the page continues to load. Upon reloading the effect is permanently there.

I can reproduce this on both personal and work computers running Windows 10. Currently using work computer Windows 10 Education v1709 x64 with a GTX 1050.

Google Chrome	63.0.3239.132 (Official Build) (64-bit) (cohort: Stable)
Revision	2e6edcfee630baa3775f37cb11796b1603a64360-refs/branch-heads/3239@{#709}
OS	Windows
JavaScript	V8 6.3.292.49

I can see the diagonal lines on https://travis-ci.org/jkcclemens/lalafell_bot/builds/329753648, https://travis-ci.org/KittehOrg/KittehIRCClientLib/builds/323823340, but ONLY after scrolling down (they disappear after scrolling to top) on http://www.digitalspy.com/tv/game-of-thrones/news/a847397/game-of-thrones-arya-stark-tom-hank-kill-list-graham-norton/.

The latter behavior is contrary to my personal computer, where the lines are immediately visible.
