And for the next version (2.10) it is planned, that "Sinc (Lanczos3)" Interpolation will be replaced by a new one that works together with GEGL.

I've seen this before but now have an easy way to reproduce. I'm not sure whether the resolutions matter, but here's how I'm currently reproducing: 1. Create a new RGB image filled with solid white, size 5616x3744 (size of 5D Mark II images, what I was editing when I found it) 2. Scale down to 1200x800 using "Sinc (Lanczos3)" Interpolation 3. There will now be a weird thatched-pattern in the image, even though it should be completely #ffffff pixels I attached the resulting image, saved as a PNG.
