Google releases new versions of it's Google Chrome web browser on a pretty regular schedule (every 6 weeks or so), and most updates go relatively unnoticed. The current one is version 37, and some Windows users have been puzzled/frustrated to see some issues with "zoomed in" fonts.
Google has released Chrome Stable 37 yesterday and with it came a new feature to improve font rendering on Windows. The text rendering was switched from Graphics Device Interface (GDI) to DirectWrite in Chrome 37 and while the majority of users did not report any issues, some users noticed that contents looked zoomed in and kinda blurry in the browser.
Most users who experience the issue on Windows seem to have set the DPI scaling to 125% instead of the default 100% value.
I was not able to reproduce the error on a Windows 7 Pro and a Windows 8 Pro system though which makes it likely that something else needs to be causing the issue.
Google is tracking the issue since Chrome 37 Beta on Google Code but it is not clear if and when the issue will be patched.Ghacks has a couple of workarounds here that you can use for now if you are experiencing this annoyance.
