Nano Banana 2 2K/4K outputs are blurry and washed out, while 1K works

Hi,

I’m seeing a consistent issue with Nano Banana 2.

1K works normally, but with the same prompt/settings, 2K and 4K outputs become blurry, washed out, low-contrast, and almost blank.

This happens on both Krea and OpenArt. Other models seem fine.

Even with a simple apple prompt, the object is barely visible and overexposed/blurred, like the high-res pass or upscale route is broken.

I also found multiple other users reporting the same issue.

Has anyone from the team looked into this? Could this be a backend or high-resolution generation issue?
