This is with libpng-1.6.21 .
Comment 1 Paweł Hajdan, Jr. (RETIRED) gentoo-dev 2016-06-14 19:57:11 UTC 
Upstream is updating libpng, see https://bugs.chromium.org/p/chromium/issues/detail?id=599917 .
Comment 2 Paweł Hajdan, Jr. (RETIRED) gentoo-dev 2016-08-01 18:00:47 UTC 
This should be fixed with https://gitweb.gentoo.org/repo/gentoo.git/commit/www-client/chromium?id=19050b84a294b9807bd6e755b75230141892f195 .
