Issue 702633  has been merged into this issue.

Cary, would you mind taking a look or finding a more appropriate owner?

Matt, is this in your code?

Yes, the overflow is in my code.

I suspect this change:
https://codereview.chromium.org/2618633004

It's in the blame range and the images from the test case seem to be animated pngs (Cool!).  Reassigning to Leon.

tsepez@ why is this labeled M58?  I think animated png is for M59?

I am unable to see the detailed report as either scroggo@chromium.org or scroggo@google.com. Can someone please give me permission?

Though I am unable to see the report, it looks like this may be related to  issue 703397 .

If that is the case, the fix is at https://codereview.chromium.org/2761193003

Okay, I'm able to see the report now. This is a dupe.
