 This is the Gmsh FAQ
 
@@ -98,6 +98,16 @@ Are you are executing Gmsh from a remote host (via the network)
 without GLX?  You should turn double buffering off (with the -nodb

+* 3.4 Why is there an ugly "ghost" triangulation in the vector
+PostScript/PDF files generated by Gmsh?
+
+Actually, there isn't. This "ghost triangulation" is due to the fact
+that most PostScript previewers nowadays antialias the graphic
+primitives when they display the page on screen. (For example, in gv,
+you can disable antialising with the 'State->Antialias' menu.) You
+should not see this ghost triangulation in the printed output (on
+paper).
