No offense taken here, I agree for the most part.

Personally I am interested in helping make Octave as stable and portable
as possible. I test and fix bugs on a wide range of GNU/Linux and UNIX
systems even though I personally only use Debian.

I want Octave to be just as useful and stable on Windows as it is on
Debian. I have no access to a Windows system to help make that happen,
so all I can do is make suggestions for others to try and ask for test
cases and debugger stack traces.

If someone is willing to give me remote access to a Windows system or
buy me a copy of Windows to install in a VM, it would be at least
possible for me to test and debug things directly.

Back to your original post, it would still be helpful to see an example
demonstrating this behavior. Is the main delay in the on-screen plotting
or in the saving to a PNG file? Is saving to an EPS file faster? Does
the delay have to do with the complexity of the figure?
