I am currently having issues with using Blender on my desktop computer where Blender just locks up/stops responding randomly while I manipulate positions of objects or node graphs. Blender never unlocks and there does not seem to be a consistent cause for this issue. All other programs run fine while Blender is locked up. My computer is not locked due to memory, CPU, nor GPU usage.

Please, if anyone can provide any information on this, I would greatly appreciate it!

Computer details:

Blender version: 3.6.1, only non-default add-on is MolecularNodes v2.7.4

OS: Pop!_OS 22.04

GPUs: GeForce GTX 1080, GeForce GTX Titan X (both pretty old, but still running strong with other visualization softwares)

GPU Driver: 535.104.05

CUDA Version: 12.2

CPU: Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz

RAM: 32 GB

Edit: just noticed that Blender is still using 100% CPU (one thread of 8) even after being locked for 15+ minutes now.

Edit 2: Added Blender version and add-on details (duh).

Edit 3: This is not arising due to loading corrupt blender files. I just started a fresh run, recreating the desired blender process for the visualizations that I am interested in, and the program still locked up.

I wonder if it is related to these:

Install intel-gpu-tools. Set GPU to max frequency: sudo intel_gpu_frequency -m

If this fixes the issue as it did for "L L", the speculation is that the root cause is related to on-demand frequency management.
