Agustin, I found that your problem can be caused by *duplicate* lines
underneath the ones you see on the screen. To check this, use v.digit
to break some of the lines and remove a small bit of each line. Then 
refresh the display and see if, mysteriously, the gap has been 'filled'.
Hope this helps,
