How do you come to this conclusion? Because of the glps_renderer? I don't know much about the internals, but the figure window is drawn by the QtHandles toolkit.

​Try replacing "\" with "/" in the gnuplot_binary. ​

Yeah, that helped! My script now opens three gnuplot figures and I can use the ___cairo devices for output!
This is definitely an improvement, thanks for your help!

For frequent plotting of large data, however, gnuplot is too slow. The new QtHandles toolkit works quite nicely for plotting on the screen, so I would love to see its printing capabilities improved. I will submit bug reports on the issues described in the first post.
