PyVista plotting running slowly, resetting box size and causing collisions

I managed to fix (hopefully) the rest of the issues with my MD simulation, but I just can't seem to get the hang of PyVista. I created this rough loop below and it runs very slowly. Like when I print the tensor calculations it takes 0.2sec and running the visualization takes 4+...

[CPU / Vectorized] Missing reduce_max() member in at::vec::default::Vectorized causing compilation error in vec_test_all_types.cpp

### 🐛 Describe the bug ### 1. Summary When building PyTorch from source on CPU/Power (or running vector unit tests), compilation fails in vec_test_all_types.cpp because at::vec::default::Vectorized (the default/fallback vector implementation) lacks a reduce_max() member...

`torch.compile channel_shuffle identity shortcut preserves non-contiguous strides unlike eager CUDA, causing downstream view to fail`

### 🐛 Describe the bug A non-contiguous CUDA tensor passed through `torch.channel_shuffle(x, 1)` and then a legal `.view(...)` works in eager but crashes under `torch.compile` on **all** backends (`eager`, `aot_eager`, `inductor`) during fake-tensor propagation. Since...
