So this means that I've been working with the PNG driver ?
IIUC, to switch to cairo, I have to set GRASS_RENDER_IMMEDIATE=cairo ?

Sorry, must have created that one myself, don't know how this slipped 
into PERMANENT.
But it was the same for any line layer.

Everything works perfectly now. Thanks !

Now that you put my nose onto it, yes, I can see it in the PNG images 
also. However, it only shows on the bottom and right, not top and left 
sides.

Anyhow, do we really want a border to be drawn by default ?

Works beautifully.

Might be nice option for the GUI: render everything which is listed for 
display in the Display window into an svg or ps file...
