Continued r/b but it looks like the frequency is not that high, on most of the retrigger results it was 2-3 failures over 21 retriggers.
As Andreea said, it moves chunks and platforms which makes it a bit difficult to bisect as it would take a number of ~20 retriggers/job/platform.

Retriggered and backfilled on pushes before https://treeherder.mozilla.org/#/jobs?repo=autoland&revision=9dc9deb3ba3bdfb7875b8259308d31ec46f4d6d1&selectedJob=287022561 - Bug 1611660 .
Last r/b got to https://treeherder.mozilla.org/#/jobs?repo=autoland&searchStr=android%2C8.0%2Cpixel2%2Cquantumrender%2Copt%2Creftests%2Ctest-android-hw-p2-8-0-arm7-api-16-qr%2Fopt-geckoview-reftest-e10s-3%2Cr%28r3%29&tochange=ed4cadb326afe38a610445b64c0e8aae9a4c78ec&fromchange=a752d438b0176eef5e241cebd4c6f119f5a21b37&selectedJob=287120266

The backout fixed the last 2 days spike, there were more than 30 failures in 24 hours, by comparison to the last 3 months when there were 82 failures.
Retriggeres after the backout was merged: https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&searchStr=linux%2C18.04%2Cx64%2Cquantumrender%2Cshippable%2Copt%2Creftests%2Ctest-linux1804-64-shippable-qr%2Fopt-reftest-e10s-8%2Cr%28r8%29&fromchange=3c25ab24bcda1aba845a0266071741a3b17e908d&selectedJob=287065073

Started to frequently fail with this push: https://treeherder.mozilla.org/#/jobs?repo=autoland&revision=9dc9deb3ba3bdfb7875b8259308d31ec46f4d6d1, failed not only on Linux 18.04 x64 QuantumRender Shippable opt but also for Windows 10 x64 QuantumRender Shippable opt and other, multiple reftests tier1 and tier2.

As Natalia mentioned, the failure rate was not that high before, but I've continued r/b up to:
https://treeherder.mozilla.org/#/jobs?repo=autoland&searchStr=Android%2C8.0%2CPixel2%2CQuantumRender%2Copt%2CReftests%2Ctest-android-hw-p2-8-0-arm7-api-16-qr%2Fopt-geckoview-reftest-e10s-3%2CR%28R3%29&tochange=bc5880b621d585ca49be49e07ee14dd32153c01b&fromchange=a8df7fffc6251beb500f194f84a8888d6bb12f09&selectedJob=287230066

In the last 7 days there have been 28 occurrences, all on android-hw-p2-8-0-android-aarch64-qr opt.

Recent failure: https://treeherder.mozilla.org/logviewer.html#/jobs?job_id=301554759&repo=autoland&lineNumber=10648

There aren't any images in that test so I don't think the linked push could cause this.

I notice that in the reftest manifest this test is listed as

fuzzy-if(geckoview&&webrender&&emulator,0-11,0-632)

and the failing tests match all of that except emulator.
