I am affected by this bug when using fltk and visible off. I worked around this by installing a shell executable like this:
===File /usr/bin/octave-cli-bug-50479======================= #! /bin/sh LD_PRELOAD=libGLX_mesa.so.0 exec octave-cli "$@" ============================================================ I strongly suggest that Debian installs a similar workaround while waiting for the ral bug to be corrected. -- Francesco Potortì (ricercatore) Voice: +39.050.621.3058 ISTI - Area della ricerca CNR Mobile: +39.348.8283.107 via G.
