Actually, I encountered this in  "normal" stack usage :-)   The Mac 
version of the problem (only droppings from selection handles) I might 
consider an IDE-only problem, but on WinXP it leaves behind remnants of 
the edges of the button itself, even with "Suspend Dev tools" in place.

I was thinking about the Space Invaders game mentioned by Nicholas, and 
thought I'd play for 5 minutes. The easiest way to handle the "player" 
in SI was to create a button, give it an image and have it move 
horizontally to track the mouse - and immediately I saw the problem.

OK - once I investigated it a bit, I discovered that making it not be 
the default button cured it, but it took me a little while playing with 
different option settings on the button to find that.

So it's certainly not a serious problem - but it's definitely a problem, 
and if I had been developing on a Mac, I wouldn't have known that on the 
PC an "unselected" button has this bad habit.
