if this question has been asked before please point me to the answer.

whenever i open a vanilla image in gimp then resize to a smaller dimension it becomes fuzzy, soft focus. to get the sharpness back i select filters - sharpen - then about 50 sharpness and all is well again. is this a setting issue or common behavior?

go down this path - after i have done this operation sometimes i have to resize the same image to a new dimension. same problem same solution. second question, jpgs are lossy. if i do this then save the jpg a second time at new dimension does this cause the same repetitive save, loss of quality problem as opening and resaving an image?

i.e. qulity-wise am i better off going back to the vanilla image and saving once for each image size as opposed to repetitive saves during one open image session?

As a matter of work flow, you would be better off to initially save your image in the Gimp's native format, xcf, do all your work on the xcf file, then when finished, save back to jpg, png whatever.

Eventually, successive saves in jpg will cause a degradation of quality, that's why it is best to work in xcf

To be pedantic; and perhaps clarify slightly. Successive save to JPEG is completely OK, successive save/load cycles are not. GIMP does not degrade the currently edited image by doing a save to JPEG, thus if all the work in scaling down and saving to JPEG is done in a single session without opening any of the saved JPEGs you are not losing any quality
at each save step.
