Version: 2.1 (using Devel) Installed from: Compiled sources When zooming images, it seems Gwenview seems to do a bad job upsampling the image, making it look very pixelated. Compare the attached screenshot showing a detail of an image zoomed at 500% with gwenview on the left side and eog on the right side.

I consider this a feature, not a bug: if your zoom ratio is higher than 200%, Gwenview disable smoothing because it does not really bring anything interesting except a magma of blurred pixel, and it prevents you from seeing the real pixels when you want to see them (for example when looking at a screenshot or at an icon).
I think it will be good if: * add option to disable this feature; * add option for zoom ratio on which Gwenview disable smothing; * disable this feature for fullscreen mode.
