ChatGPT Image 2 is broken – weird artifacts 90% of the time

It's almost unusable for img2img tasks when you need to maintain character consistency via image prompt. These weird artifacts keep appearing: repeated patterns, spots, dots, etc. I don't even know how to describe it, but it looks pretty trippy.
This happens even with a fresh image in a new chat window.
We also need the option to switch back to ChatGPT Image 1.5. Please fix it.
