I get white grey strips/ on the copper filled part of the PCB.
I dont really need to explain just look at the picture ( open it ), this happens with almost all of my boards whenever i export a pdf. Since im home etching i can just open gimp and paint them one by one using the bucket tool, but its an just an extra annoying step when dealing with a complex double sided PCBs
there has been older discussions about it before
but it looks like there no progress to report …
