Glitch nodes and splines get misalligned

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

The nodes and splines remain connected in the viewer.

### Actual Behavior
Nodes and splines get misalligned:

### Steps to Reproduce

For me it happens when I leave comfyui open overnight and gets resolved on a restart. I use remote desktop which might be affecting it not sure.

### Debug Logs

```powershell
no debug log
```

### Other

_No response_

The issue names no source files, tests, or entry points. First reproduce the misalignment after leaving the viewer open overnight, ideally with custom nodes disabled, and compare the node and spline positions before and after; done means they remain connected without requiring a restart.
