Public bug reported: I'm running Unity with a stacked multi-monitor configuration. My (1366x768) laptop display is located under a larger (2048x1152) external display. I've set the external (top) monitor as the "primary" monitor that holds the dock and the menu bar.
In this configuration, the wallpaper is misaligned with the screen border. The wallpaper on the top screen is shifted down around 20-some pixels and shows up on the bottom screen. I've attached a screenshot showing the issue, with a big red arrow to direct your attention the issue. (It's more subtle on the screenshot than it is on a live system.) This issue doesn't seem to cause any functional problems.
