Andy, I have made some changes to the code. Can you test the
patches. I hope the artifacts are reduced this time.

The artifacts are still there.

To be a bit more precise 2 and 4 seem to be artifact free, unless I
didn't find the right sample/scale factor. The others show similar
artifacts to those seen previously.

There is an offset so all images are down and left a bit, though this is
often not obvious, when scaling down from 2160p to 1080p it causes a
white line left and top which is very visible.
