This seems like a good opportunity to ask a question I've wondered
about once or twice. Does XQuartz use apple libraries to render the
content of windows, or simply request a raw window and draw on it
outside those tools, or some combination? If it's the latter, this
would all make sense. The 'capture image of window' item which is
being used must operate at a lower level than the other associated
tools, since it can capture the entire window regardless of wether
it's all on screen or layered under others without having to raise or
clear the window, something one can't do with the fully rendered image
sent to a screen.
I remember wondering about this when I first tried that feature but
never took the time to look into it further, could be interesting to
find the answer, especially to why some work and some don't. Seems
like any part of an xterm which has text in it currently is saved
correctly, but other parts are not, then every single graphical
program I have fails EXCEPT, the small ones that come with X11 (xeyes,
xlogo, etc). Very strange.
In the mean time, selection works just as well, if taking very
slightly more time.
