Zoom,Fit,Center
I'm running Pop 20.10 and HydraPaper 2.0.2. My monitor configuration is 2 x 34inch monitors (3440x1440) and 1 x 27inch (2560x1440 in portrait mode. The wallpaper mode (zoom, fit, center) seems to work well with the 27inch in portrait mode, but does nothing in both my 34inches in landscape mode. Changing to any modes results in wallpaper being in zoom mode all the time.
