[Trisquel-users] Bug with my toolbar ?!

[marc-antoine . cardia]

Hi !!

I've got some trouble with the "toolbar" of gnome. I want to change the  
background of this toolbar but there are some artefacts :

see this image if you don't understand.

I want to change the default colour (grey) of this toolbar. But, with this  
bug, I can't have good results.

I want to change the color of this toolbar in white because I like the design  
of Mac OS X. But this OS is not free at all ! So I use Trisquel, and I want  
to change his look.

Can you help me please ?

PS : Sorry for my English, I'm French and I don't write very well in  
English...
