:jet this is debug only (the ccov builds are debug but reported as opt)- I recall recently a bug we were ok disabling on debug instead of adding fuzzy-if()- do you have a preference for this bug? here is a reftest-analyzer link: https://hg.mozilla.org/mozilla-central/raw-file/tip/layout/tools/reftest/reftest-analyzer.xhtml#logurl=https://queue.taskcluster.net/v1/task/GcRFec2cTAG-WOkv4A5bRw/runs/0/artifacts/public/logs/live_backing.log&only_show_unexpected=1

We surely don't want to add 9000+ pixels of fuzz to fix this, and it also happens on release builds. There's a downscale-during-decode timing-sensitive bug under here, and I think we still want to fix it (see bug 1383682 comment 35 for the diagnosis.)
