Wallpaper "Smart" fit isn't.
Larger than screen res wallpapers run off the edges of the screen
I've got WindowBlinds 8.06 (029 x64 Windows 8 Edition). I have a number of wallpapers that are larger than my 1920x1080 screen resolution. Windows native wallpaper display deals with these just fine when set to 'Fit'. Windowsblinds doesn't seem to have a setting that can deal with these tho. 'Smart' results in the wallpapers being displayed at, as far as I can tell, their native resolution, so a 2000x2000 image, for example, loses nearly half the picture. That doesn't seem very smart to me.
