You can nuke them pretty easily with - who could have guessed - typical antialiasing strategies;
Code:
FTurnRight()
a=last
FastLineDarkenMOD(64,211)i
af=merge(a.SangNom2(0,24),a.SangNom2(1,24))
aff=af.FTurnLeft()
SeparateFields()
Merge(SangNom2(0,24),SangNom2(1,24))
AssumeFieldBased()
Weave()
FTurnLeft()
Merge(aff)
Spline36Resize(1280,720)
And I'm not even sure if the extra "separatefields() ??? weave()" part is even necessary.
You can remove it for a nice increase in performance should you find it unnecessary.
