After I imported a large gallery, several of the images inside are displayed in an odd way. I am unable to zoom out or move the image around, and the dimensions are displayed as ?x? in these images.

Attempting to preview the image in its own popout window provides a similar outcome, but allows to zoom in and out. Toggling from "Full size" to "Overview" and then back to "Full size" relocates the image to the corner, but takes away the ability to zoom.

I noticed this bug after importing a large folder containing scanned A4 pages, totalling 169 pages which amounted to 269MB.
