Thanks for your reply Dave! hm... that's what I thought at first, since the windows-version is so incredibly blurred.
However, I can't put my finger on it, but the characteristics of this edge-noise just seem strange to me... The edges of objects seem to be too distorted to fix by some plain-vanilla GIMP filters (blur + sharpening afterwards?), since they introduce a lot of aliasing effects - but if you say that the image is "technically spoken" correct, I'll try to find a useful postprocessing effect chain in GIMP to apply.
