What happened

When switching between different checkpoints invoke starts to produce corrupt images.

Here is an example of a corrupt image. Below is the image that invoke produced after restarting (same settings & same seed)

What you expected to happen

Switching to different checkpoints should not negatively impact the generation process. I.e. generating an image after switching between checkpoints several times should produce the same output as generating an image with the same settings right after starting up invoke

How to reproduce the problem

Start up invoke and queue up images. They can use the exact same settings and prompt, but each image should be generated with a different checkpoint.

After generating 3-5 images (this number might be hardware dependant) invoke starts to output corrupt images exclusively. Every generation, even with checkpoints that worked well before, produces images that look like noise.

Some more examples:

Additional context

Rolling back to version 4.2.7 fixes this issue.
I can reproduce this error since version 4.2.8

Generating several images with the same checkpoint works fine in all versions.

Thanks for confirming when the issue began. Strangely we haven't had other users mention this to my knowledge.

Can you please share the hardware and macOS info from Apple Icon -> About This Mac?
