This is a subtle antialiasing difference at the very point of the ">" twiddly arrow for the "> Summary" chunk here.

This test is already annotated as slightly fuzzy (originally in Bug 1316430) and maybe it's a bit extra fuzzy on Android.

If this happens again, let's just adjust the fuzzy annotation.

The latest failure matches the description in comment 1 (the white pixel just to the right of the point of the ">" has a very subtle difference between the two screenshots) -- rgb(255,255,255) vs. rgb(251,251,251).

I'll land a patch to adjust the already-existing fuzzy annotation to allow for this mismatch.
