Background problem in Joomla 3.x

We used Steak House template for Joomla 2.5 template, and everything worked fine. Recently we upgraded our website to Joomla 3.4.3 and we upgraded the template as well. Since we did that upgrade, we're having problems with module backgrounds on the homepage. They don't cover the entire module background but look broken, as if three backgrounds of different sizes are overlapped behind the module content (like a mosaic, but with some empty space). This happens only on larger screens - 1920 px and more. How can we fix this problem? Please see www.blendologia.eu

Hi

Can I please see a scrrenshot with this problem ? I've checked the code and background already have a "background-size: cover;" value included, so as this function works is to fill whole the screen. Also I have 1920 px screen and do not experience it at all.

Hi,
Thanks for your reply. I'm attaching images of background problem.

Hi

I'm afraid it does not look like that for me at all. Please tell me what screen dimensions are You using. I believe it's way pass the standard website width.

Also, are You using skype ? My nick is "teitbite", please add me and I'll try to check this problem directly from Your computer while shearing screen.
