On some of my posts, I include an occasional application screenshots. The better ones that I have done may look something like this one of f-spot (which I made when frustrated with the quality of a screenshot in a presentation I was reviewing).
You might notice that it has really nice shadowing. Too nice. Casual consipracy theorists could get the idea that my blog might be supported by a cadre of Novell graphics people as part of a underhanded–even dastardly–marketing effort by Novell.
For everyone else, the cool shadowing is simply courtesy of Compiz, the compositing manager that sits atop Xgl or AIGLX and provides all the cool Desktop Effects in SUSE Linux Enterprise Desktop 10.
However, if you have ever tried to screenshot an application while using Compiz, have probably found some issues.
First off, the Alt+PrtSc key combo that usually can grab a screenshot of the currently active window does not grab the window decorations (title bar, mainly) on the window under Compiz.
