The text that is part of the refusal is not targeted to your asset. It's simply stock text that is attached to any "Quality issues" refusals. Conclusion: just give us the heading, that is enough for us.

Thanks a lot for pointing these out! I really appreciate you taking the time to mark the rendering issues so clearly. I'll make sure to review my assets at 100–200% zoom before submission next time and fix these artifacts. Your feedback is super helpful! I used to upscale images using Upscayl. I have attached a screenshot here.
