Created attachment 192232 [details] simple file with image Sometimes a thin border is visible at the right side of an image, but when going to print preview it disappears. This is annoying, because it could also be a bug in the image. See example ex.odt.
You will get the thin border, which show the whole rectangle, which has been filled by the image. Change the anchor to "As Character" and it will be shown around the whole image, because it will work better with every zoom level.
Right or bottom border is seen at various zoom levels. It disappears if menu View - Text Boundaries is unticked. Not sure if a bug.

Either all borders are marked or none. Only the right one is a bug.
