May be related to the fix landed for bug 1753019

I don't think so (though I suppose it's hard to tell with this new approach of lumping failures from all subtests into a single bug).

I think it's just the issue we diagnosed in bug 1737725 comment 11, which was previously tracked in several bugs (basically, one per message which usually meant one per subtest) including bug 1737725, and is now tracked in this "single tracking bug" for the test group.

We do plan to work on a fix for this underlying issue in 2022 H2 (it's in our Stabilization Sprint 2a). I'll assign this bug to myself to reflect that.

I hope the sheriffs will afford us some leniency until that fix is in place (since this aggregation method now means the intermittent failure rate is above the disable-recommended threshold of 30/week, but nothing actually changed/regressed, we're just grouping more things into a single bug).

Thanks for the logs! I'm new to how intermittent failures are tracked, but bug 1785026 was cased by bug 1782921, which landed just a few hours ago, so I think the bugs are a little different. I'm currently investigating bug 1785026.

The bugs are different but might have the same regression Bug (Bug 1782921) that's why I mentioned the tier 2 bug.

I may be missing something, but the regression bug (bug 1782921) landed just a few hours ago, well after test_group_hittest-2.html became perma (bug 1776972 comment 23). I'd guess bug 1776972 comment 5 and bug 1737725 comment 11 still point to the cause of this intermittent.

This bug's original line is this: TEST-UNEXPECTED-FAIL | gfx/layers/apz/test/mochitest/test_group_hittest-2.html | helper_hittest_bug1730606-2.html | root scroller (after async scroll) scrollid - got 213, expected 211 but because of the new thing all the bugs are merged into one with the file name | single tracking bug but now the curent failure line is: TEST-UNEXPECTED-FAIL | gfx/layers/apz/test/mochitest/test_group_hittest-2.html | Fixed ancestor should not be hit .
"Fixed ancestor should not be hit " just like Bug 1785026.
I think you can Ignore the original fail, because this is different.
Aryx when you have the time can you help me with a more detailed explanation for Dan?

Comment 23 is when this test was disabled on some platforms, because its intermittent failure rate was too high (but not close to "perma").

The sharp increase in failure rate on remaining platforms (going "perma") is more recent and does coincide with bug 1782921 landing. Basically, it's the same issue as bug 1785026, it's just that for some reason, some failures contain "unknown test url" instead of "test_group_hittest-2.html" in the failure line and so get associated with bug 1785026 rather than this one.

(May be related to the fact that helper_hittest_fixed-3 includes SimpleTest.js directly, which is known to cause problems with printing the test name.)

Looking at which subtests are failing, out of 52 failures over the past week, 23 are in helper_hittest_iframe_perspective-3.html, and 22 are in helper_hittest_iframe_perspective.html, with the remaining 7 being spread out across various other subtests at a low volume.

Given that, my plan is to do the following:

Quarantine the two affected subtests in a new test group, which is disabled on windows11
File a follow-up to track investigating the high failure rate of those two subtests on windows11 and track re-enabling them on that platform

Filed bug 1829010 for this. (I realized I probably shouldn't land patches in this bug, since this is the "single tracking bug" for the test group and as such it will stay open anyways to track any remaining failures in the test group. I will land any patches in separate bugs instead.)
