This bug is blocking CQ for blink CLs because the test often fails with patch and succeeds without patch. My CL and several other CLs failed multiple times on win_chromium_rel_ng causing CQ to fail.

We're getting flakes in windows again.

Should the benchmark be disabled?

Comment 14 by mastiz@chromium.org, Jul 7 2017 

I think yes. I will go ahead and revert https://chromium-review.googlesource.com/c/562510/, please follow up later with reenabling.

[System health] Update infinite scroll logic to wait for scroll_height expansion


Before this, upon scroll being stuck, we wait for 1 second then retry scrolling.
This wait time may not be enough on some slow machine, hence we change the logic
to wait for document.body.scrollHeight to expand which is more portable. This wait
will timeout after 30s in case the page is badly stuck.

This also reenables browse:social:twitter_infinite_scroll which is flaky on
Windows bot on Chromium waterfall (which is a VM instance).

Summary: "benchmarks.system_health_smoke_test.SystemHealthBenchmarkSmokeTest.system_health.memory_desktop.browse:social:twitter_infinite_scroll" is flaky on Windows (was: "benchmarks.system_health_smoke_test.SystemHealthBenchmarkSmokeTest.system_health.memory_desktop.browse:social:twitter_infinite_scroll" is flaky)
The crash stack in #19 shows "blink::PaintLayer::HitTestContents". I assign this to chrishtr@ who last touch PaintLayer.h

Comment 25 by chrishtr@chromium.org, Aug 1 2017 

Did it just recently start crashing? (Is there a commit range?)

Comment 27 by nedngu...@google.com, Aug 2 2017 

Actually around 07/07 since there is no flaky report between 06/02 & 07/07.

Comment 28 by chrishtr@chromium.org, Sep 11 2017 

I think it started failing after this commit:
https://chromium-review.googlesource.com/c/chromium/src/+/562510

Which means it was failing on windows before 7/7. I also looked at patches
around that time and there was nothing.

This is failing lots of CQ runs, and seems to affect all platforms. Still crashing in paint stuff:

[1:1:0123/201338.787558:FATAL:PaintLayer.cpp(2210)] Check failed: !result.InnerNode() || (result.GetHitTestRequest().ListBased() && result.ListBasedTestResult().size()).
