Hi,

I know the right thing is to do a fully comprehensive writeup but I don't have the energy!
Criteria required to recreate bug:

Different size and shape wallpapers on the monitors (NOT uniform shapes per display)
"Fit Best and maintain Aspect ratio" (great feature by the way, all good wallpaper apps offer this)

When you enable / disable some displays, the wallpaper will 'leak on' to other displays, wrapping around, all kinds of weird stuff.
Problem has been in the package for at least 9 to 12 months, I've just not bothered reporting it.
Anyone else?

Thanks Keith, it was off on my setup, surely this is now a default option though, right?
