<div dir="ltr">Hi Sean,<br><br>I ran in to this a few months ago. The best we could determine was that it was a bug in the AMD binary driver. The problem seems to be explicitly limited to the AMD binary + OpenGL2 backend. Can you try running the build you have against llvmpipe to confirm?<br><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr">----------<br>Chuck Atkins<br>Staff R&D Engineer, Scientific Computing<br>Kitware, Inc.<br><br></div></div></div></div></div></div></div>

I built paraview master (with Qt5.6 if it matters) and it got as far as the splash screen before segfaulting when I tried to run it. Here is a stack trace from GDB [1]. I'm travelling right now, but I'll be back in time for the hackathon tomorrow. Maybe we can look at it then.<br><br></div>Shawn<br><br>[1]:<br><span>Program received signal SIGSEGV, Segmentation fault.<br>0x0000001500000001 in ?? ()<br>(gdb) where<br>#0 0x0000001500000001 in ??
