I was hoping I’d manage to get something going with this but it’s
completely fine here. Does the line blank, then redraw, then the image
loads in its new buffer?

Something is blanking the line. There are only so many places where
that happens so in theory it should be relatively straight‐forward to
find the place in question. Perhaps start by commenting out the
NSRectFill commands in ns_clear_frame and ns_clear_frame_area.
