The problem is that google chrome shows some weird vertical and horizontal lines in my website.
I think is a render problem but I’m not sure.
Google chrome version is 18.0.1025.168

And i have checked for extensions, my google chrome doesn’t have any.
The problem is not on the browser, neither on your website, I tested here on my installation of Google Chrome 18.0.1025.168, and no problems found as you can see on the image below:
Note:
I had that problem in the past, and was a graphic driver problem.
I believe that it is a graphic driver problem on the computer you are using!
