Issue descriptionUserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36 Example URL: https://jsfiddle.net/Lf1cxo7f/ Steps to reproduce the problem: 1. Navigate to the JSFiddle above 2. Mouse over the four spans What is the expected behavior? The hovered span should become "active" and become lighter, but the background and rest of the heading should remain the same What went wrong? Blocky artifacts are displayed randomly, made worse by mouse movement Does it occur on multiple sites: Yes Is it a problem with a plugin? No Did this work before? Yes Chromium build 440007 Does this work in other browsers? Yes Chrome version: 61.0.3163.100 Channel: stable OS Version: 10.0 Flash Version: Shockwave Flash 27.0 r0 Also posted to StackOverflow with no response. https://stackoverflow.com/questions/46591972/seeing-blocky-artifacts-in-chrome Not sure that Chromium build 440007 was the last version where it worked, but it definitely worked then. Versions after that started displaying large solid black blocks and then shortly after began showing the black artifacts it currently displays.

Could you try Chrome Canary and see if the issue still reproduces there?

sorry for the delay -- missed this one. the change in c#3 is entirely code that's compiled only for android. it's definitely not affecting win 10. i'll try to narrow it down.

I cannot reproduce this on Canary 64.0.3242.0. I can reproduce on Stable 61.0.3163.100 but only after downgrading my NVIDIA driver to 353.62. Rob, is it possible this is the D3D11 clear issue given the version of Canary that did repro in #3?
