Details:

Hi,

I have an installation of Fedora 26 with the standard Octave v4.2.1 build
deployed. In setting the graphics backend to qt, then plotting graphics within
a loop, it causes some of the graphics to fail to plot.

Command to set graphics backend :

graphics_toolkit ("qt");

Script that causes the failure has been uploaded (loop_graphicsv2.m)

Regards,
Shadders.
