Webkit transition not working on chrome with windows 8.1

Question

I'm implementing a themeforest template and having a weird issue with chrome on Win 8.1.

The CSS is using -webkit-transition to fade in divs.
Weirdly, this is not working only on chrome and windows 8.1.
Windows 7 or 8 with the same chrome version(latest), works just fine. also on ubuntu.
On IE10, also perfectly.

Here is a link for the template preview.

Anyone has any idea? Maby GPU issue?

Thanks, Roi.
