Well, assuming it is mipmapping (which it may well not be!) the
easiest way I know of is to install ccsm ($ sudo apt-get install
compizconfig-settings-manager), open it, click on Advanced Search,
type mipmap into the filter, then go through each plugin in turn and
make sure the Mipmap checkbox is empty.
If this doesn't fix it, try running unity --replace in a terminal and
seeing if any descriptive error messages are shown when it starts
