Package: octave
Version: 4.0.0-3
Severity: normal
Starting Octave from a terminal with --no-init-file --no-site-file
brings up the GUI interface. I get this:
GNU Octave, version 4.0.0
[...]
» graphics_toolkit
ans = qt
» plot(1:2) # fails
» graphics_toolkit fltk
» plot(1:2) # fails
» graphics_toolkit gnuplot
» plot(1:2) # succeeds
The failure of the first two plot commands is very similar: in both
cases the window pops up and the menus work, also the status line
showing the position of the cursor works. Only, the content of the main
window is blank (and never refreshed, in fact the menus appear to never
close). For the qt backend, the content is "transparent", that is, set
to the content of the window below. For the fltk backend, the content
is grey.
