>From https://code.google.com/p/chromium/issues/detail?id=266427:

UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.95 Safari/537.36

Example URL:
http://jsfiddle.net/cjgammon/Dxkpr/1/

Steps to reproduce the problem:
1. apply a background color
2. apply a background image
3. multiply the bg color or apply other blend mode (non solid color)

What is the expected behavior?
it should blend with the background color

What went wrong?
it does not blend

Does it occur on multiple sites: Yes

Is it a problem with a plugin? No 

Did this work before? Yes seems to work in canary here: https://git.corp.adobe.com/pages/gammon/background-blending-demo/index.html

Does this work in other browsers? N/A 

Chrome version: 28.0.1500.95  Channel: stable
OS Version: OS X 10.8.4
Flash Version: Shockwave Flash 11.8 r800

the short-hand syntax seems to blend correctly.
For example: 
    background: url(''https://www.google.com/images/srpr/logo4w.png''), #fefefe;
