Comment 3

[Dorel Luca [:dluca]]

This bug failed 44 times in the last 7 days. All fails are on Windows 7, Build types pgo, opt and debug.

Here is a recent log of the failure:
https://treeherder.mozilla.org/logviewer.html#?repo=autoland&job_id=146590831&lineNumber=3678

And here is part of the log:
05:55:03    ERROR -  REFTEST TEST-UNEXPECTED-FAIL | file:///Z:/task_1510723742/build/tests/reftest/tests/layout/reftests/writing-mode/ua-style-sheet-textarea-1.html == file:///Z:/task_1510723742/build/tests/reftest/tests/layout/reftests/writing-mode/ua-style-sheet-textarea-1c-ref.html | image comparison, max difference: 255, number of differing pixels: 8658

Hi :jet: Can you please take a look at this bug?

Comment 4

[Jet Villegas (inactive)]

Smells like the same issue as:
https://bugzilla.mozilla.org/show_bug.cgi?id=1374075#c10

Comment 5

[Jonathan Kew [:jfkthame]]

Yes, it looks like it.

Looking in the reftest logs for "Dumping JSON representation of sandbox", the failing runs show "windowsDefaultTheme":false, whereas "normal" passing runs have "windowsDefaultTheme":true. Why the difference?

This reminds me of bug 1411490 comment 10. It looks as though for some reason, occasional reftest runs are seeing an environment with a different theme setting, or are failing to properly detect the windows theme, or something.

Do the failures seem to occur on specific machines, or randomly on any machine?

I believe this is an issue where we have windows 7 not having a consistent theme, please see bug 1343049

[Tiberius Oros[:tiberius_oros]]

There have been 43 failures in the last week

This is occurring only on the Windows 7 platform.
As for the build type, I see 4 occurrences on debug, 16 on pgo and 23 on opt.

Comment 10

[Jonathan Kew [:jfkthame]]

As noted in comment 7, this is caused by bug 1343049. There's nothing to be done here aside from fixing that. (Bug 1423658 will turn this into a clear infrastructure failure instead of looking like an individual test issue.)

Comment 23

[Arthur Iakab [arthur_iakab]]

This bug has failed 49 times in the last 7 days. It failed only on Windows 7, affecting opt, pgo and debug build types.
Failing test: opt-reftest-gpu-e10, opt-reftest-no-accel-e10.

Link to a recent log: https://treeherder.mozilla.org/logviewer.html#?repo=try&job_id=158972164&lineNumber=3837 

This bug is blocked by bug 1343049 which depends on 1433851. So we are waiting for a resolution on those bugs.
