I'm late on this but yes, with at least linux and Windows when you're
using hardware rendering and grab the contents of the window, you get
whatever is currently displayed on your screen within the bounds of the
drawing area of your IDLgrWindow. IDL is just copying the PC's frame
buffer. Software rendering or rendering to an IDLgrBuffer (which also
uses the software renderer) doesn't suffer from this limitation since
IDL has access to the data before it is copied to the frame buffer.

This is a bit of a issue since I generally prefer to use hardware
rendering for the anti-aliased output it generates so when creating
animations I have to be really careful not to move the mouse over or pop
up another window in front of my IDL window.
