Have GNURadio installed on Ubuntu 15.10. I have been running simple_ra but don't believe that is germane to the problem at hand.

I am running simple_ra_receiver under debug (have seen segmentation errors in libc in the past and trying to narrow down) but, again, don't think this is a factor in the symptom.

    Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/plotter_base.py", line 209, in _on_paint
    for fcn in self._draw_fcns: fcn[1]()
File "/usr/local/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/plotter_base.py", line 65, in draw
File "/usr/lib/python2.7/dist-packages/OpenGL/error.py", line 208, in glCheckError
    baseOperation = baseOperation,
OpenGL.error.GLError: GLError(
    err = 1285,
    description = 'out of memory',
    baseOperation = glCallList,
    cArguments = (2L,)

   The graphics screen is frozen (grey) but the rest of the threads run OK.
In terms of system memory, shows 1.9GiB of 15.6 so I don't believe the system is running out of physical memory.

   Cannot find anything relating to this issue vis-a-vis GNURadio.

Any ideas of what is going wrong or a workaround I could implement to avoid?

           Kind Regards,
