Created attachment 2815 [details] One line patch which fixes the problem opt_complementary = "-1:r--fo:f--ro:r--fo"; ^^^^^ ^^^^^ "r--fo" is repeated twice. It should look something like this instead: opt_complementary = "-1:r--fo:f--ro:o--rf"; regards, Davide
Thanks! Fixed in git, will be in 1.19.x
