This package seems to require libglvnd-dev on ubuntu

[hmaarrfk]

sudo apt remove libglvnd-dev
wget https://raw.githubusercontent.com/vispy/vispy/master/examples/basics/scene/grid.py
python grid.py

# Segfault will happen
sudo apt install libglvnd-dev
python grid.py
# Segfault will not happen

could be an issue with vispy too :/

[hmaarrfk]

python -vv grid.py outputs:

/lib/python3.7/site-packages/PyQt5/QtTest.so'
import 'PyQt5.QtTest' # <_frozen_importlib_external.ExtensionFileLoader object at 0x7f38116ea828>
import 'vispy.app.backends._qt' # <_frozen_importlib_external.SourceFileLoader object at 0x7f38117565f8>
import 'vispy.app.backends._pyqt5' # <_frozen_importlib_external.SourceFileLoader object at 0x7f381354c908>
Segmentation fault (core dumped)

Which is why I opened the bug report here.

Are you able to reproduce this without vispy?

[hmaarrfk]

do you know how to activate opengl? Spyder which runs on qt was fine, just opening my opengl assets was making my whole python crash.

Not offhand no. Though it would be good to isolate this issue further.
