Public bug reported: I've installed Lubuntu 12.10 on a system with four displays arranged horizontally totalling 6160 pixels horizontal resolution. I created a wallpaper image that places a different picture on each screen. The left two screens are not displayed correctly. See attached images (both scaled to 1/3 size).
It seems like there is some kind of strange layering issue. If I click on the desktop on the leftmost screen, I get the result shown in the screenshot. If I then click on the second-left screen (that shows the incorrect image), anywhere on the desktop that's showing the incorrect picture (i.e. roughly the right half of the screen), the wallpaper changes, so that both screens are displaying the picture that should be shown on the leftmost screen, identically (the second screen's wallpaper is not visible anywhere). The other screens' wallpapers display fine. This is using "Tile the image to fill the entire screen" setting in Desktop Preferences; other settings don't let the image span all four screens correctly.
