Issue: [Bug]: Restarting the webui.sh will cause inconsistency.
Labels: bug-report

### Is there an existing issue for this?

- [X] I have searched the existing issues and checked the recent builds/commits

### What happened?

By restarting the webui.sh, I found that different webui.sh processes have difficulty generating identical images consistently.

Sometimes they generate identical images, sometimes they don't.
i.e., if you try 5 times in a roll, you may find out that they are not identical.

### Steps to reproduce the problem

1. Startup webui.sh.
2. Generate a simple txt2img.
3. Terminate webui.sh.
4. Startup webui.sh again.
5. Generate a simple txt2img with the exact same parameters.

It's "possible" that the 2 images are not identical, in file size, or maybe I can even notice some subtle differences by just comparing them.

### What should have happened?

I expected all the images are identical.

### Additional information

It's consistent as long as I don't restart the webui.sh, even if I reload different models it'll still be OK and identical.
