I've just completed a fresh first install of Ubuntu 64-bit 12.10 and very regularly the on-screen text is distorted.

How could I fix this?

Looks like a problem with the video driver. Which GPU are you using? – Dennis Feb 14 '13 at 14:30

Issues with the pre-installed drivers are rather common in Ubuntu 12.10.

I haven't tested them myself (because I don't have an nVidia card), but the drivers from X Updates seem to solve those issues for a lot of people.

You can install the drivers by executing the following commands from a terminal:

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current nvidia-settings
