Comment 1

[Daniel Holbert [:dholbert]]

Notably, this was a Linux x64 QuantumRender (i.e. webrender) test run.

It looks like this test is currently "expected fail" due to a known rounding error, tracked in bug 1103286.  The original test failure annotation is here:
https://dxr.mozilla.org/mozilla-central/rev/9055d9d89a4bca5cf48dda789299559aefca4e54/layout/reftests/w3c-css/submitted/images3/reftest.list#186
...though this bug was actually filed for the copy of this test in web-platform-tests, which is (unsurprisingly) also annotated as failing, here:
https://dxr.mozilla.org/mozilla-central/source/testing/web-platform/meta/css/vendor-imports/mozilla/mozilla-central-reftests/images3/object-position-svg-001o.html.ini )

In the reftest.list file linked above, there are actually a number of other tests that are marked as "fails-if(!webrender)" -- i.e. they pass specifically with webrender enabled.  Maybe webrender ameliorates bug 1103286 somehow, and that's helping with this test as well? (sometimes at least)

Comment 2

[Kartikaya Gupta (email:[e-mail])]

I agree with comment 1. A little odd that it's intermittent, though. I wouldn't expect a failure due to rounding-error to only happen intermittently. We can wait and see how frequently this gets hit, I guess.

So.. this annotation now looks like [1] - it was changed to fails-if(!webrender) in bug 1458968 which landed right around when this intermittent started. However, if that reftest (in layout/w3c-css/submitted) is consistently passing, I don't see why the wpt copy would only intermittently pass.

[1] https://dxr.mozilla.org/mozilla-central/rev/6b9076ac236cb0f9f301bc601eac03f9ec4205df/layout/reftests/w3c-css/submitted/images3/reftest.list#186

Comment 5

[Kartikaya Gupta (email:[e-mail])]

I verified that layout/reftests/w3c-css/submitted/images3/object-position-svg-001o.html and testing/web-platform/tests/css/vendor-imports/mozilla/mozilla-central-reftests/images3/object-position-svg-001o.html are identical files, as are the corresponding object-position-svg-001-ref.html files.

I also looked at the m-c pushlog since bug 1458968 landed [1] and the Wr1 job fails (with unexpected-pass) a bunch of times on the object-position-svg-001{e,o}.html tests, while the regular reftest jobs are 100% consistently passing.

So to me this implies it's some sort of difference between our mozilla reftest harness and the wpt reftest harness that's causing this difference.

[Kartikaya Gupta (email:[e-mail])]

I'd be ok with skipping this test for webrender. The intermittent result is basically useless and the non-WPT version of this test is passing consistently.

[Andreea Pavel [:apavel]]

This was in the wrong component. Kats can you fix this or should I ni someone else?

Comment 30

[Kartikaya Gupta (email:[e-mail])]

I can fix it, sure. But the component was correct, see comment 5.

I did not notice that. I searched for the component with mfi: https://irccloud.mozilla.com/file/uDIRz199/image.png
