<p>Hi,</p>
<p>Thanks for your kind consideration. I have run the ctest Python
tests and they all run fine.</p>
<p>I am still trying to workout why the script would crash and I
have found out that it will crash (under Linux) when the
interactor is started. The same script on the same data works fine
with VTK 7.0 OpenGL2 under Windows 10.<br>
</p>
<p>Just in case, I am attaching a minimal script that demonstrates
the problem. The script will load python pickled data that I have
saved in a single file available at: <a
class="moz-txt-link-freetext"
href="https://www.dropbox.com/s/me8cbtjh9p8qfid/data.pck?dl=0">https://www.dropbox.com/s/me8cbtjh9p8qfid/data.pck?dl=0</a></p>
<p>The script displays the data, waits 5 seconds, and than starts
the interactor (crashing).</p>
<p>Best Regards,</p>
<p>Andrea</p>

initializing OK and running. So it could be something specific

work? ala

<div>thats runs 1/23rd of the python tests </div>

All,<br>
<br>
I have successfully compiled VTK 7.0.0 under
Ubuntu 16.04.1 LTS on a computer with the
following hw configuration:<br>
<br>
Processor: Intel Core i7<br>
<br>
GPU: NVIDIA GTX Titan Black<br>
<br>
---<br>
<br>
VTK has been configured for:<br>
<br>
OpenGL 2 back-end<br>
<br>
Use Qt 5.7<br>
<br>
Use OpenMP for SMP<br>
<br>
Wrap Python 3 (ver 3.5.2 on the system)<br>
<br>
---<br>
<br>
A simple python script which displays an
unstructured grid and which works fine under
Windows, opens (under Ubuntu) a rendering window
and crashes with the message below:<br>
<br>
X Error of failed request: GLXBadDrawable<br>
Major opcode of failed request: 154 (GLX)<br>
Minor opcode of failed request: 11
(X_GLXSwapBuffers)<br>
Serial number of failed request: 111<br>
Current serial number in output stream: 111<br>
<br>
<br>
Do you have any hint about this? Should I try the
RC 7.1 or switch to the plain OpenGL back-end ?<br>
<br>
Thanks in advance for any suggestion,<br>
<br>
Best Regards,<br>
<br>
Andrea<br>
