Lightroom Classic development mode "fill" is only using a quarter of the image panel.

Images load full-size (filling the screen on the longest edges) normally when viewing an image in the library.

But when I switch to develop mode the image reopens in the upper left quarter of the editing screen. Sometimes it opens on top of the full-size preview image, sometimes in a new window. If I change from “fill” to “100%, it just gets bigger in that quarter so you can only see the center of the image.

This just started after trying to balance text sizes on my other programs and lightroom. So it might be related to that. Or it might be related to closing and reopening lightroom multiple times. For a hot minute I actually had a readable font size, but that also disappeared when this started.
