Moreover, I faced the similar grid while downscaling many other landscape pics
with huge flat - but not absolutely flat - surfaces, be it sky hit by noise a
bit, or a sea-view with a small waves. So this

So, if you scale down to 51% (which is about 2x) you first do a 2px
Gaussian blur. Result here:

Hi!
After installing new Gimp 2.8 (on Lubuntu 14.04 64bit) for our employee, she
