More information.
I have 2 monitors. One is 1600x1200, which is the main one (monitor 1). The other is 1280x1024, which is the secondary one. As stated previously, the secondary is to the left of the primary.
Here is a screenshot. Explanation below.

Ignore the black border around the 1600x1200 image on the right, it's the way the image is; same goes for the black bars on the top and bottom of the left, since it's a 1280x1024.
Bottom right of entire screenshot. See the grass through the taskbar? It's supposed to show through the ENTIRE taskbar, not just the bottom right. Now, look at the Ultramon Smart Taskbar on the left. Notice something wrong? It's showing the bottom of the RIGHT SCREEN WALLPAPER (notice the green grass color).
This is what I'm talking about. It does this no matter what drivers I use, no matter what program I use for dual-wallpaper, and no matter what options I set.
If anyone knows how to point me in the right direction concerning this, I'd appreciate it. And show me some screenshots if you say that there's no bug.
