DL'l your "original" and viewed on openSUSE Tumbleweed in geeqie, gimp and
imagemagick (display) and do not see the "grids" even after pushing to
200%.  Scaling "method" appeared to make no difference, nor did
resolution.  My installed gimp package is from openSUSE Build Serice.

kde4 4.14.6
gtk3 3.16.0
gimp 2.8.14
