I've seen it on a few apps/images, but the most readily-apparent one is in
the TextEdit app that I've been porting (trivially -- mostly fixing
GNUstep bugs) to GNUstep.
grab <http://www.d2dc.net/~deek/TextEdit-work.tar.gz>.
Compile and run TextEdit.
Info->Info Panel...
You'll see two images; one of the application icon, the other saying
"TextEdit". Both images have alpha, but the text image's drop shadow shows
the bug nicely.
It starts out looking normal, but if you click on it, the drop shadow gets
darker. Click again, it gets darker again.
