Steps to reproduce the problem:
1. Start Chrome on a Surface Pro 4 with the latest drivers from Windows update (Windows 10)
2. Ensure hardware acceleration is turned on
3. Go to a page with a light-weight font such as https://www.continuum.io/downloads

What is the expected behavior?
Chrome should render fonts according to the Windows 10 system settings (ClearType), as Firefox and Edge appear to do.

What went wrong?
Chrome renders light-weight fonts badly with hardware acceleration turned on (and the rendering is still much different to, and less readable than Firefox and my PDF reader even with acceleration off). 

The attached image shows, from left to right, the page https://www.continuum.io/downloads rendered in Chrome Canary 53.0.2767.0 (clean install) with acceleration *on*, Chrome Stable 51.0.2704.84 with acceleration *off*, Firefox 47.0 with acceleration on, and Sumatra PDF rendering a PDF of the web page.

Note that Chrome Canary and Chrome stable show identical behavior.

This is all on an external monitor (100% scaling in Windows display settings) on my Core i5 Surface Pro 4, which has Intel graphics, running Windows 10 Pro (1511).

Did this work before? Yes Approx 2 months ago on Chrome Stable, definitely was working in January.

Chrome version: 51.0.2704.84  Channel: stable
OS Version: 10.0
Flash Version: Shockwave Flash 21.0 r0

Disabling DirectWrite on Chrome Stable makes no difference.
