Package: octave
Version: 4.0.0-4+b1
Severity: normal
Dear Maintainer,
thanks for your work in octave for debian :-)
I'm using it to perform some basic exercises for the university.
When executing a file (attached, lab1_1.m) via octave-cli two plot windows are
created, but then both
windows hangs and the terminal hangs as well.
My desktop is XFCE4 and I suspect that my old graphic cards may be part of the
cause...
Graphic card (from lscpi):
