Hello, im punchikk i been having problems with my other email account , so i created this one. Yesterday i send a message to the pd list  but  since is gem related i think here is the more appropiated place , so here it goes:

in my gem patches when i have 2 or more geos that overlap i always get artifacts or glitches between them, why does these artifacts appear? is there any way of avoiding them?
ive tried the same patch in 2 different computers and i get the same results , any idea?

here are some pics:
