[I think gtk related] From I update my system, I have more space between horizontal lines of text

[Xan]

Hi,

I updated my system and now I have more space between two consecutive lines of 
horizontal text (in gedit, xfce-calendar, ...; any gtk based application). I 
think that it's gtk related, but I don't know why. Do you have any idea about 
that?

Thanks in advance,
Xan.
