Details:

Here's the content of my polarp.m file. Simple enough.

theta = 0:0.01:2*pi;
rho = (sin(3*theta)).^2;
polar(theta,rho);

Octave plots the graph using "OpenGl", but if I click on the drawn graph, then
all of Octave crashes.

Also, if I choose instead to use "gnuplot", then NO graph shows up in the plot
window. But, it does plot o.k in "fltk", but I would rather the opengl toolkit
(If I can call it that), if only because it looks better and has some better
interface features.

I tried playing around with various "Advance" features of KDE in Desktop
Effects in System Settings; compositing type, qt graphics system, etc. But the
same outcome. I ran Octave in Openbox as well, instead of KDE; again same
outcome.

FYI, my system is PCLinuxOS 2014.12 64 bit KDE Platform V 4.14.10, running on
an ASUS laptop (i5, 8 GB, Intel Graphics HD 5500 ), linux kernel 4.1.3-pclos1,
3.0 Mesa 10.6.5.

Attached is the various scenarios with each toolkit, the opengl one is
however, a small ogv video (880 Kb).
