I am still new to Ubuntu. So far I love it and honestly want it to work right before steam is released on it, so far everything is running correctly except some of the text on my computer is glitching up.

That is a link to see what I'm talking about.

How do I stop this problem?

My specs:
Intel core i5 Quad 3.60 GHz
NVIDIA GTX 550Ti 1GB DDR5
8GB DDR3 memory
500 GB Hard Drive
My motherboard is ASUS but I forgot the exact model.
