Different wallpaper per-monitor

I used to use Hydrapaper to set a different wallpaper on each monitor, but it’s broken as of F36. I see the “spanned” scaling option is also gone, so I can’t stitch the images together in GIMP. feh doesn’t work either, presumably due to Wayland. As a result, I’m stuck with the cool new color-changing wallpapers cropped and zoomed-in 300% on my portrait monitor.

It seems like this was a deliberate choice from the GNOME developers: The big background cleanup (#4936) · Issues · GNOME / gnome-shell · GitLab

Can anyone suggest a workaround? I’m trying to stick with Wayland.

Did you try the flatpak of hydrapaper from flathub, it looks to be more up to date.

I did, but no dice. The flatpak at least opens, but it doesn’t have any effect on the wallpaper image.
