transparent xfce-terminal - vim problem, looks like selected text
 

Hello. I have Debian Wheezy on my desktop.
It was difficult to explain the problem on the title. I use xfce4 and vim on (partially) transparent terminal. The problem is that when i open a file with vim (no matter what colorscheme i use), then scroll down and again up, the background becomes transparent and the text looks like somehow "selected". My colorschemes are normally not transparent. I use xfce and the exact same vim configuration on my laptop and have no problem there.
I have attached an image so that you understand what i mean, and my .vimrc file.
Can you figure out the problem?

Are the settings for xfce4-terminal the same on both your desktop and laptop? Check ~/.config/Terminal/terminalrc on both machines.
