Although I noticed the segfault with mesa configured and built with : ./autogen.sh \ --with-driver=xlib \ --disable-gallium \ --without-demos make -j 8 Because I have never been able to produce a working offscreen VTK with mesa configured this way, and since -fvisibility=hidden was added the ./autogen.sh way did not even build VTK untill the cbf30fce322506bd43692617de9d201533f41532 change. and that was about the same time that offscreen rendering stopped working for me no matter how I built mesa, my git bisect script uses : make -j8 linux-x86-64-debug so -fvisibility=hidden is not added to the command line of the builds in the git bisection.
