Details:

Hi. On Kubuntu 20.04, when I plot anything in GNU Octave, lines and curves are
plotted with weird patterns of colors, as the attached image shows.

First, I used the default Octave package in Ubuntu (.deb). Then in order to
get rid of this problem I uninstalled it and installed the latest version of
Octave with Flatpak instead. Nothing changed unfortunately.

This problem only occurs if linewidth is equal to or less than 1. So with the
default value of linewidth this problem occurs.

This computer also has Windows 7. On Windows there is no such problem.
