878f71061b8eWorked: Never worked with Metal backend, always worked with OpenGL backend.
Short description of error
When closing a Matplotlib graph window, Blender instantly crash.
It's related to Metal backend.
Exact steps for others to reproduce the error
It doesn't crash when using the OpenGL backend (which has been removed since Blender 4.0).
It doesn't crash when using Python3 outside of Blender.
Here attached are 2 files :
Metal backend + Matplotlib = Blender crashto Metal backend + Matplotlib = Blender crash (MacOS)Update :
Attached a new blend file to demonstrate this finding.
Hi, thanks for the report. I'm not sure if we track bug reports caused due to external python libraries.
@lichtwerk ^
Understandable ^^
Matplotlib is a must-have for anyone doing data science/statistics though.
Let me know what you think and if you have any clue about the crash, maybe I'll try reporting on the project's Github.
Are you able to upgrade your system to at least macOS Ventura (13.6.x) or even Sonoma (14.1.1)...? Metal support in those macOS version has been changed / improved...
