Follow-up Comment #1, bug #53186 (project octave):

I forgot to mention that it is already possible to print an invisible Qt
figure if it has been visible once. So for testing properly one should use
something like:

close all
figure ("visible", "off")
plot (1:10)
print /tmp/invisible_print.png
## Change the size of the figure to test framebuffer object
set (gcf, "position", [0 0 1200 1200])
fr = getframe (gcf);
imwrite (fr.cdata, "/tmp/invisible_getframe.png")
