Hi,

Sorry to disturb. 

When an image is opened in fullscreen mode, it is resized automatically. I wonder what interpolation method is used over there. From

eog-scroll-view.c:1409 interp_type = CAIRO_FILTER_NEAREST

I guess for zooming the CAIRO_FILTER_NEAREST method is being used.

Please correct me if I am wrong. 

For the initial render or while zooming CAIRO_FILTER_NEAREST is used for responsiveness.

Once you stop zooming and the corresponding settings are enabled (they are by default) a second pass will redraw the image with CAIRO_FILTER_GOOD shortly afterwards.

It makes no difference if you have eog running in fullscreen or windowed mode, btw.
