Do you have a graphics card install. Click the unity button, then go to additional hardware, make sure you have a graphics card, or a driver installed.
from your screenshot, can't tell if it is a font issue or a graphics issue.
If it is a font issue, try this:
all that means is you installed the fonts to ~/.fonts or somewhere in your local user folders and it is not accessible to all users.
you have 3 main ways of installing fonts, the first one is the one that is causing you issues. the second way is to install them using ubuntu software center. and the 3rd way is to do it manually. I recommend you to do the following steps.
You will need to enable the Universe and Multiverse repositories
sudo apt-get install ubuntu-restricted-extras
this will install all the windows fonts and they should be accessible to all users.
