Ok I found the culprit : I have an add-on that registers a bpy.app.handlers.save_pre function that manipulates the context.
Here is a clean unglitched file with minimal code to reproduce the…
Thank you for replicating. I'm going to do a clean install and investigate the origin of the first glitch.
I found a way to reproduce the issue reliably !
Steps :
- Open UI_bug.blend
- do : `File > Defaults > Save Startup…
Thanks for the Load UI trick ! Do you know if there's a way to troubleshoot / debug an issue like this ? There should be some kind of error somewhere i guess ?
Well I think that reduce the window diminishes the number of pixels to be rendered, thus the better responsiveness. Consider that the Blender viewport fullscreen is 4K, by reducing it to a…
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…
Update :
- by default Matplotlib use the "MacOSX" rendering backend
- if I install PyQT6 and force Matplotlib to use "QtAgg" to render, it doesn't crash anymore !
Attached a new blend file to…
I can confirm, no issue in MacOS 12.5, using Blender 4.0.
@Andrew-Herman can you reproduce the issue in Blender 3.6 and choosing "OpenGL" in Preferences > System > GPU Backend ?
No lag here on my MacBookAir M2.
- What's your computer and/or CPU ?
- Can you reproduce the issue in Blender 3.6.5 by choosing "Metal" in Preferences > System > GPU Backend ?
- Can you share…
Can't reproduce on MacOS using Blender 4.0.0. Can you share a blend file ? Do you use a custom theme ?
@ideasman42 Thanks for taking time to clear that out, it makes sense.
You are correct about the use case : my add-on already uses Matplotlib which also freezes Blender while its window is open,…
This has been intentionally removed.
Closing.
Is it to encourage people to use bpy and Blender native interfaces ? or some other technical reason ?
(I'm running into the same…
