Answer by PurpleAlien for Chrome 33 shows ugly, blocky, pixelated fonts in Linux

This seems to be a bug in Chromium with the Helvetica font. It is discussed here:

https://forums-web1.gentoo.org/viewtopic-t-984870.html?sid=d8fa5b8fc9ae0c83520d1769dc366d58

From that thread, this solution fixed it for me:

• make the following files in some empty directory
• go to chrome://extensions
• check the developer mode box
• Load unpacked extension
• point to the new directory

manifest.json

{ "name": "Fix Helvetica", "description": "Fix Helvetica", "version": "0.1", "content_scripts": [ { "css": [ "Custom.css" ], "matches": [ "http://*/*", "https://*/*" ]   } ], "manifest_version": 2 } 

Custom.css

@font-face { font-family: 'Helvetica'; src: local('Arial')}
