Description

[Justin Lebar (not reading bugmail)]

First occurred on my push, d124391343a0.

These look pretty busted; there are white horizontal bars through some text and whatnot.  I don't know how long the link below will survive, but here's a link to the reftest analyzer:

[Matt Brubeck (:mbrubeck)]

This sounds like the same thing (e.g. white horizontal lines through text) and affected many of the same tests.  Curiously, it happened at the same time as a large but different set of test failures in a different build (Linux32 debug) on the same push *and* yet another large set of test Linux32 reftest failures in a totally unrelated push on Aurora.  Could this be infrastructure-related?

Comment 2

[Ed Morley [:emorley]]

Mass marking whiteboard:[orange] bugs WFM (to clean up TBPL bug suggestions) that:
* Haven't changed in > 6months
* Whose whiteboard contains none of the strings: {disabled,marked,random,fuzzy,todo,fails,failing,annotated,leave open,time-bomb}
* Passed a (quick) manual inspection of bug summary/whiteboard to ensure they weren't a false positive.

I've also gone through and searched for cases where the whiteboard wasn't labelled correctly after test disabling, by using attachment description & basic comment searches. However if the test for which this bug was about has in fact been disabled/annotated/..., please accept my apologies & reopen/mark the whiteboard appropriately so this doesn't get re-closed in the future (and please ping me via IRC or email so I can try to tweak the saved searches to avoid more edge cases).
