Mats: Any ideas on the increase in failures here? (Pinging you since it looks like you - once upon a time - reviewed the fix for bug this tests against.)

Maybe bug 1488871 affected this test somehow?
kats / tnikkel probably knows more about how this test works...

There seems to be a big spike from Oct 16 - Oct 19, which doesn't seem to correspond to any activity on bug 1488871.

Not really, although it doesn't seem super complicated. It looks like the test synthesizes a keyboard scroll, which seems to work since the first part of doneScroll() runs and passes checks. I suspect the second part (which synthesizes an APZ wheel scroll) also executes, but then the scroll doesn't happen. To see why, check out the screenshot of the failure - it's just a tab switch spinner. Having the tab switch spinner up means the compositor doesn't yet have all the necessary info, and so APZ will probably just discard the wheel scroll.

I'm going to do some backfilling to see when the Oct 16 spike really started, hopefully that will give us a culprit.

Yeah, emilio noted that it got backed out but the bug was never reopened
for some reason, so it can't be related that bug.

The regression range I'm getting [1] is not looking too useful. But I guess the larger problem here is that the test is trying to invoke APZ code without actually waiting to make sure APZ is ready. This would probably explain the slow trickle of intermittents going back more than a year as well. I can try to write a patch for this.

All the failures in that try push are for bug 1499996 so the patch seems good.
