What happened

After generating a couple of images in version 4.2.8, invoke stops creating proper images. Whenever this happens, the issue seems to persist until invoke is restarted - every single new generation produces a blur of colors like in the example below.

After restarting invoke, i generated the exact same image (same seed and metadata) which created a normal output:

What you expected to happen

Generating images with identical metadata should have reproducible results.

How to reproduce the problem

Sadly i can not pin down the cause yet. It feels like switching models a lot between generations (i.e. queuing up the same prompt with different models for comparison) makes this issue appear more often.

I tested 4.2.8rc2 only briefly, but had the same issue once in the release candidate as well.
