I'm trying to set up different wallpapers for my two monitors, but whenever I try to apply it in DisplayFusion, the images don't format correctly. It seems like the program is trying to squeeze the two images into each monitor or something.

Where the red line is (to the left of the icons) is where the split is between the two monitors

Having similar issue.

I had a similar situation happen with Afterburner installed along with AMD/ATI drivers while trying to install display fusion. I uninstalled Afterburner and restarted and everything was fine. I haven't tried Afterburner again since. I don't know if this might help or if maybe it's something similar.
