Here's a weird suggestion: app Y can take screenshots of
the canvas in app Y using java.awt.Robot api every N
seconds and see if anything changed since last time by
diffing the screenshot images (coarsely).
Of course, this may give false positives if something
obscured the canvas, as well as false negatives if app X
keeps re-rendered the same thing, not to mention
that it won't be very performant. In short, an excellent
solution!
Thanks,
Dmitri
