Follow-up Comment #12, bug #53073 (project octave):
I too noticed the FLTK toolkit doesn't exhibit this problem. It does do a
redraw of the whole framework window (and presumably the plot as well) but I
don't see any sort of momentary change in the interior plot area appearance.
Then again, FLTK isn't quite the same setup as the Qt setup, is it? I think
the Qt toolkit might be essentially no more than switching the OpenGL context
from nVidia driver to gl2ps driver, whereas FLTK's graphics engine might be
more indirect in the sense that there are drawing routines that then call
opengl routines.
I'm not 100% sure, and I really don't want to dig that far into graphics, so
the extra "drawnow()" route is fine, but in a way that avoids an additional
drawnow() for FLTK or gnuplot toolkits because those two already seem to
redraw after the print for one reason or another.
