[Morgan Reschenberg [:morgan]]

Looks like this is sometimes p1 and sometimes p2 -- but always 10px more than what we should be getting. It's also always failing in the fission iframe, not the regular iframe. Investigating.

Comment 11

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Is there an ETA for the fix or should the test get temporarily disabled, given the failure volume?

Comment 12

[Morgan Reschenberg [:morgan]]

I've been poking at this but can't reproduce locally (and not seeing any immediate errors in the way the test was built). I'll disable this under webrender.

Reopening this bug because it did not have the leave-open keywords and the flags changed to fixed when the disable patch got merged to central.

Btw the disable is made only for windows. This is still failing, recent failure log: https://treeherder.mozilla.org/logviewer?job_id=354981088&repo=autoland&lineNumber=1917
