VTE 15.05 - NEW GRAPHICS

Hi everybody,
I upgraded from 4.5 to 15.05 this week.
A topic talking about the new version reported:

"VTE Free evolves into Community, renews the graphic but remains for free"

Except for the welcome screen, I don't see any graphics change...
Even in the login page too... it seems the new login request is in foreground, but the old stays in background... (I attach an image).
It's normal? Or it's possible that somethig went wrong during installation?
However, I see all data, and everything works fine.
It's a Linux Installation... on Ubuntu 12.04 LTS.

Thank you,
regards
Giuseppe

Solved login... it was my browser.
However I can't see any difference while using the CRM.
