Running paraview 3.8.1 (see http://paraview.org) on a Linux client
(Mandriva 2010.0 or Red Hat Enterprise Server 5.5) causes a crash of
my Cygwin/X (release 1.9.2.0) with Segmentation fault at address
0x306. Any ideas?
Paraview uses OpenGL. Perhaps that is related.
Thanks.
Here is the backtrace. Thanks again.

I have not tried other OpenGL programs, but I can run glxinfo without
a crash on either machine. I attach the results. They are not the

I would suggest that for an application like ParaView, you will probably get
much better performance if you use the experimental hardware accelerated
OpenGL -wgl mode, see [2] for details.

Anyhow, can you try with 'GLWIN_NO_WGL_EXTENSIONS=1 XWin -wgl -multiwindow'
Thanks. I did this and it worked. However, for a particular paraview
dataset that I happened to have lying around it is slower

Once I say -wgl, direct rendering no longer works. That is, if I
don't set LIBGL_ALWAYS_INDIRECT, then I get a long (infinite?)
sequence of errors like this:
