Background.. broken?

I have a strange issue with my background:
http://warper.ru/
There are stripes as you can see.
It is happened after I edited php and css files of VIRTUEMART (I did not touched pixellove template's files)
Please, help me if you know how to fix it.
Thank you

I just also noticed that font's size now is to big.

There is a topic
https://www.gavick.com/forums/pixellove ... 16887.html
where Teitbite helped me to solve couple of similar problems.
I dont know if it is me, or some error =/ sos

I've learned how to change font's size.
Also, checked my template.css and overide.css . I'm not good enough in css to find the problem, but alteast main_bg file is not corrupted.

Does not matter, moved to another template.
