Hello Janek,

For me, the crash only happen when I open and then close the 3D view
from the controller. Otherwise the simulation itself is fine.

I tried to open the controller without actual running anything. I just
copy and past everything from the terminal to here just in case:

The crash happened when I closed the "Show 3D" window. Here is the
message from the terminal:

<DEBUG> GLViewer:50 virtual void yade::GLViewer::closeEvent(QCloseEvent*): Will emit closeView for view #0
<DEBUG> OpenGLManager:52 virtual void yade::OpenGLManager::closeViewSlot(int): Closing primary view.

Thank you.


Best regards
Jiannan
