I have a WPF project that has been working just fine. But now, it's doing this thing (see picture). I don't really even know how to describe this. It's happening on all the windows. If you make a change using any of the controls the desktop shows through the window. What causes that?
The orange part on the second screen capture is from Snag It. Can you see how whatever is directly behind my window shows up? It hasn't done this before. Thanks for any help on this.
