Ubuntu – Graphical artifact in Chrome and Chromium

Since today I encounter weird graphical artifact when using Chromium ( makes it unusable).

It does not happen in Firefox or any other application.

Here is a screenshot :

(Not visible in the screenshot but this also happens to the menu/tab bar. Not only in the page content.)

Out of curiosity I installed Chrome but the exact same thing happen.

I was wondering if it is a known problem with one recent update or if the problem come from my graphics card ?
