Note that all 6 tests that failed have about:blank as a reference.

Attachment: Relevant part of the log

The reference image has a red dot in the lower right corner

Comment 2

[Mats Palmgren (inactive)]

The six reference images are exactly the same.

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

Since we cache images, we presumably rendered it once with the dot and then cached that bad rendering.

Comment 4

[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).
