Bad quality image generations

Hi

For the past few days, generations with Chroma have been poor quality. The generated images look like heavily compressed JPEGs. I haven’t changed anything in my workflow and I don’t understand what’s going on.

I tried rolling back to a previous version and completely uninstalling/reinstalling ComfyUI, but nothing works.

The issue names no files, tests, workflow, model, version, or environment details. Start by collecting the exact Chroma workflow and generation environment, reproduce the compressed-looking output, and compare it with the earlier version mentioned. Done means identifying the regression and verifying a correction with a regression check.
