I’m using both WordPress and Google Chrome for many years, and I never encounter any issue. Both work very well until recently when Google Chrome automatically updates itself when restarting my computer. This issue maybe surfaced much earlier, but I rarely shut down my Laptop & Chrome, so I only find out there is font rendering issue with the latest chrome and WordPress. Currently, my Google Chrome is version 37.0.2062.103 m & it having this problem.
The problem will only affect WordPress back-end. The versions I’m using are 3.92 & 4.0. I never try earlier version of WordPress. It also seems to be limited to Windows 8 Operating systems (Windows 8.1 included). Try Windows 7 and Windows Server 2008, this issue does not arise.
If you are having this problem, there is a way to fix it. It is not that your computer affected by virus or malware or our WordPress hacked.
To fix it do the following.
1. Open a new tab & go to chrome://flags/
2. Find “Disable DirectWrite Windows” & click enable
3. Restart Google Chrome
