Follow-up Comment #2, bug #48176 (project octave):


== with respect to bug #46861 I tried 2 aproaches ==

* apply the patch from
http://hg.savannah.gnu.org/hgweb/octave/rev/030d4d6c2b58#l1.1 to set
inverthardcopy = "off" and recompiled octave.
  this does *not* remove the problem

* in the octave gui I issued the following commands (">>" is the gui prompt)

** with default graphics toolkit ("qt"):
  
  >> figure(2,  "inverthardcopy", "off")
  >> plot([1,3,2])
  >> figure(1)
  >> plot([1,3,2])
  >>
  
  remark: the prompt comes back, even for figure(1), which does *not* have the
inverthardcopy argument


** with graphics toolkit "fltk":
  
  >> graphics_toolkit ("fltk")
  >> figure(2,  "inverthardcopy", "off")
  >> plot([1,3,2])

  
  remark: the empty line above ist the missing prompt!
  although the promt does not come back, I can type blindly and the commands
are executed as normal.



** with graphics toolkit "gnuplot":
  
  >> graphics_toolkit ("gnuplot")
  >> plot([1,3,2])
  >>
  
  works as expected

* the CLI-version (octave-cli) does *not* show this kind of problem

== hardware config ==
the two computers have both a nvidia card with the non-free nvidia-driver,
however in different versions (debian-testing and debian-stable).

another hint might be the following:
connecting from computer 2 (without this problem) to copmputer 1 (which has
the problem) via ssh and x2go (to get through the OpenGL stuff)
does *not* show this problem.
