Bug description

Hi! The short of it is this repo when run with Temurin 17.0.7 on Windows 10 is having intermittent crashing issues. It should reproduce within 10 runs. The crash occurs within a second or two on a bad run. I've narrowed it down to the remesh method in electrosphere.render.Mesh.java . I have tried Temurin 17.0.7 and 20.0.1. Let me know if there's anything else I can provide!

I've found that because the initial mallocs using BufferUtils aren't freed, OpenJDK is failing to free class memory sometimes and it subsequently crashes.
