Comment 4

[Robert Longson [:longsonr]]

That patch increased the fuzziness of a different reftest, my fix isn't the underlying cause. Something's making the reftests non-isolated.

Comment 5

[Robert Longson [:longsonr]]

This bug doesn't make sense. The reftest is already marked as fuzzy in a way that should prevent this. I've no idea what's going on here.

Comment 6

[Robert Longson [:longsonr]]

Ahh the 1035 needs to be 1044 because it's skiaContent.
