Freeform corkboard custom background image not scrolling

I am trying to implement a (large) custom background image in Freeform corkboard view, but it keeps tiling and is “fixed”.
Although these corkboard templates seem to work on Mac, do they work on Windows?
Do I have to check an option somewhere to make this custom image “scrollable” somehow? I would like to see it in its entire width, not only a small portion.
Many thanks in advance!

Will tile but if use small seamless tiles looks good did starfield background.
