Hmm, I guess it was more than that one failure that was reported here then.

Windows and Linux have:

Found 101 pixels different, maximum difference per channel 60 on page 3

So if someone could reland it with 100 changed to 120 (for good measure) would be appreciated...
Otherwise, I'll get to it eventually.

[Mats Palmgren (inactive)]

Allowed 0-120 pixels different, maximum difference per channel 76-76
Found 101 pixels different, maximum difference per channel 60 on page 3

My bad, I forgot that you have to specify a range for maxDifference as well for it to work sanely.
So 76 needs to be 0-76
