New user of Linux here.
This just started happening. As you can see in the image below, the text and icons in the Software Center are turning into strange blocks. This doesn't seem to be affecting any other application besides Google Chrome, in which the text in the URL bars will occasionally become similarly looking glitchy blocks. This isn't inhibiting Ubuntu's performance here - everything still works when clicked and in Chrome's case, the blocks fix themselves when I click them - but it certainly isn't attractive and is making reading and using the Software Center inconvenient. Any idea on why this is happening and how I could fix it?
The screenshot in question showing the graphical error as follows
Some background on what I recently did that may have caused it. I recently tried installing GNOME 3.4, following the instructions listed here but it didn't work. I figured I did something wrong, recognized my place as a general noob and gave up, uninstalling "gnome-shell" via the terminal hoping to clean up my mess.
Then, later after reading some stuff about updating from the beta to the final 12.04, I ran a dist-upgrade. It was after this that these graphical errors began to happen.
I tried uninstalling and reinstalling the Software Center to no avail.
Thanks for your time!
