I have the following page loaded in a test environment.
To start, the fonts are properly licensed and have been downloaded from myfonts.com and declared as follows:
@font-face {font-family: 'HelveticaNeueLT';src: url('css/webfonts/3019F7_2_0.eot');src: url('css/webfonts/3019F7_2_0.eot?#iefix') format('embedded-opentype'),url('css/webfonts/3019F7_2_0.woff2') format('woff2'),url('css/webfonts/3019F7_2_0.woff') format('woff'),url('css/webfonts/3019F7_2_0.ttf') format('truetype');}
@font-face {font-family: 'HelveticaNeueLT-Bold';src: url('css/webfonts/3019F7_1_0.eot');src: url('css/webfonts/3019F7_1_0.eot?#iefix') format('embedded-opentype'),url('css/webfonts/3019F7_1_0.woff2') format('woff2'),url('css/webfonts/3019F7_1_0.woff') format('woff'),url('css/webfonts/3019F7_1_0.ttf') format('truetype');}
@font-face {font-family: 'HelveticaNeueLT-Light';src: url('css/webfonts/3019F7_3_0.eot');src: url('css/webfonts/3019F7_3_0.eot?#iefix') format('embedded-opentype'),url('css/webfonts/3019F7_3_0.woff2') format('woff2'),url('css/webfonts/3019F7_3_0.woff') format('woff'),url('css/webfonts/3019F7_3_0.ttf') format('truetype');}
If you look at the page in Chrome for PC (v47), you will see that the text is highly pixellated, most evident in the Contact Us button. In Chrome for Mac, the button is crystal clear. As a rough estimate, this is 30% because the Chrome for Mac rendering engine rendered the page more clearly and 70% because I added the following code to the CSS rule for the button:
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing:grayscale;
Does anyone have any thoughts as to what is going on here? You can check out the stylesheet to see if anything there helps troubleshoot the issue.
