Filed for QuantumRender, with a handful of barely-fuzzy pixels around the fringes of a filtered element. Unless we get reports on another platform, it seems likely this is QuantumRender-specific --> reclassifying. (If needed, it looks like this could be easily worked around with a fuzzy-if annotation.)

Did some retriggers and found that 25% of the jobs are failing. It seems that the failure started here: https://treeherder.mozilla.org/#/jobs?repo=autoland&filter-searchStr=debug-reftest-e10s-2&tochange=118b16b6ab5d880813f2d5904effad16ca3dcfaf&fromchange=a6bd62970a9fb094f223d99fbdf3dac25ec2f42d&selectedJob=174546061
Thanks Noemi, this is great information. It does in fact look related to bug 1453688, :kats, is this something you want to fuzzy-if for webrender, or look into the update from bug 1453688 ?

I'll probably end up fuzzy-if'ing it, but I'm doing retriggers on the try pushes in that bug to see which upstream webrender change introduced it. /me doesn't like nondeterministic behaviour

Based on retriggers on https://treeherder.mozilla.org/#/jobs?repo=try&revision=4596e218893d805e3bac46188edbf7c7255d3224&group_state=expanded and https://treeherder.mozilla.org/#/jobs?repo=try&revision=88a378263fca4e4cbdb349df61cb1f74c25380e1&group_state=expanded it seems to have been introduced by this range: * 565e2408 Auto merge of #2661 - jrmuizel:tiled-blob-renderer, r=kvark |\ | * 71cb1d0a wrench/blob: Only paint the dirty rect * fba1b411 Auto merge of #2651 - glennw:cache-text-shadow-3, r=kvark * d48fe709 Add basic infrastructure for caching Pictures, enable for some blurs. i.e. from servo/webrender#2651 (the other PR just touched wrench).
Filed https://github.com/servo/webrender/issues/2675 for it upstream. I'll land a fuzzing patch, but let's keep this open until the underlying issue is fixed.
