For some weeks now image quality has been terrible in chrome. I've checked the flags to make sure nothing has been enabled by accident. I've also reinstalled chrome and cleared the search history.
Here is the same image open in chrome(on the left) and in internet explorer: http://i.imgur.com/7MEdwt4.png
This has been recognized as a bug, and there's now a workaround provided in response #62: https://code.google.com/p/chromium/issues/detail?id=492379#c62
