If border-radius is added to the above testcase, it works. Looks like paint invalidation issue. (Ex: https://jsfiddle.net/nLg2eo4j/3/)

Additional info: the same bug occurs in Chrome 51 on Windows 10.

Additional test cases: http://www.quirksmode.org/css/backgrounds-borders/attachment.html contains a test case with and without the border-radius.

It fails when we promote the layer to composited scrolling. That is, it fails on HighDPI devices including Mac Retina displays.

Duplicate.
