Looking at the first 2 mismatching data URIs from the first log[1] in comment 15's orangefactor link: these are input fields with a gradient background (from the native theming), and the gradient is positioned 1px higher in the "expected" snapshot as compared to the "but got" snapshot. As philor already noted here (via a dependency), this is a version of bug 1223198, since this is linux+ASAN-specific and since this seems to have gotten bad (in comment 3) around when that bug was filed. So, the real fix is for someone to figure out bug 1223198. In the meantime: since this is a particularly frequent orange and this mochitest isn't intending to specifically test native widget rendering, we can probably work around this by using an unthemed widget in this mochitest. (-moz-appearance: none) [1] https://treeherder.mozilla.org/logviewer.html#?repo=mozilla-inbound&job_id=18530884

Here's a workaround to stop the oranges, per comment 16. (Kind of a paper-over, but not really because the test will still test what it intends to test, without triggering this tangential & barely-noticeable GTK+ASAN-only rendering glitch. And bug 1223198 still covers that issue.)

Ignore comment 18 - that was bug 1234409's patch, which I accidentally landed with a mis-pasted bug number.

Looks like this worked! The brasstacks link in comment 25, looks like the only instances of this since the landing are on mozilla-aurora. I'll backport this to aurora soon. (and I don't think we need this on beta, because beta has gtk3 disabled per bug 1227024 -- and this bug here only seems to be problematic in gtk3-enabled builds, as discussed on the broader bug 1223198.)
