The scribus seems to apply antialiasing to the images.
Pixsels is visible in GIMP, but not visible in Scribus.

I think that is what is causing the phenomenon.

It is not antialiasing which cause this as antialiasing is explicitly disabled in cairo when drawing images. It might be the downsampling Scribus performs when loading images for screen display.

Whatever it is, it's very irritating if you have to judge the quality of a layout. ;)
