[Bug 969675] [NEW] Failure in some kind of visualization on Firefox (i.e.: wikipedia)

[Maf]

Public bug reported:

I've tried to open the page of Wikipedia and I'm not able to read any of the content (see attachment). So I think It's a visualization issue. The same appen when I try to open other web pages.
I'm on Ubuntu 11.10 running Mozilla Firefox 11
