Status: UNCONFIRMED

(Core :: Graphics: Text, defect)

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:37.0) Gecko/20100101 Firefox/37.0
Build ID: 20150402191859

Steps to reproduce:

On a completely new firefox install, disabled "use hardware acceleration when available".
Go to an affected website, eg.
1. Go to https://xkcd.com/1506/
2. Click on big red link
3. Scroll down and read text on the left "our policy regarding your personal data"


Actual results:

Some text is rendered badly - see attached screenshots. It looks much thinner than it is supposed to, making it difficult to read in places.


Expected results:

Text should look similar (or better) with hardware acceleration disabled (it is often listed as a troubleshooting step for badly rendered text).

GDI rendering, Chrome vs. Nightly. Note the roughly 1px tighter spacing in Nightly compared to Chrome.
