Google Chrome color inconsistency

In google chrome, the same color sometimes appears differently. I took a couple screen shots and zoomed in, and you can see that sometimes, there is a reddish halo around the type, and other times there isn't. This happens on the same element. Sometimes the type gets rendered with the reddish halo, and sometimes it doesn't.  
I cannot provide a link to the page. This is a huge application that requires authentication. I'm hoping there is some Chrome specific issue that others have discovered and been able to find a work around for. I've tried playing with -webkit-font-smoothing, but it had no impact on the intermittent red halo effect. In the screenshots attached I am not using any -webkit-font-smoothing (and I'd prefer to leave it that way unless absolutely necessary).
