Terrible quality after first batch

Closed this issue · 7 comments

When both batch size and batch count are set to values >1, the first batch is generated normally then only the first image of any successive batches in the job are correct. With batch size 2 with batch count 2 the first 3 images will all be normal quality and the 4th looks similar to generating with a typical negative prompt in the regular prompt field. For batch size 4 with batch count 3, images 1-5 and 9 will generate normally, while images 6-8 and 9-12 will look like negative prompts. This occurs even when not using any of the AND, AND_PERP or AND_SALT keywords.

Steps to reproduce:

  1. Set batch size and batch count both to values of 2 or more.
  2. Generate a set of images using any prompt and negative prompt combination.

Examples:

Batch count 2, batch size 2 with Neutral-Prompt extension enabled in Extensions tab:
grid-16894

Batch count 2, batch size 2 with Neutral-Prompt extension disabled in Extensions tab:
grid-16902

Prompt: superb, 1girl, multicolored hair, pastel colored hair, pink hair, blue hair green hair, light green eyes, short hair, fluffy hair, curly hair, pixel-print hoodie, leggings, pixel-print sneakers, beautiful 8k wallpaper, extremely detailed, intricate
Negative Prompt: negative_hand, (KHFB, AuroraNegative), (Worst Quality, Low Quality:1.2), border, nsfw, skimpy, grayscale, multiple_girls, (watermark:1.2)

This was tested using the latest commit of this extension: ab5c46d

Also, I just realized I generated the set that has Neutral-Prompt disabled with no upscaler selected for Hires fix which is likely the cause for the differences in images 1-3. Obviously the actual problem image is far more than just a difference in upscaler so I won't bother to redo that set.

I went ahead and redid the disabled grid to confirm my assumption about the blurriness/pixelated effect and make sure that wasn't due to the extension.

I went ahead and tried to reproduce the prompt inversion issue with adetailer and neutral prompt active, but I am unable to reproduce.

I updated adetailer to Bing-su/adetailer@a1032d8 (which was the version you were using) and neutral prompt to ab5c46d (latest at this moment).

Adding --opt-sdp-no-mem-attention to launch args does not change anything.

The problem is now fixed for me after updating WebUI to 394ffa7 and adetailer to a1032d89 as well as a few other extension updates. I'll go ahead and close this issue. Thanks for looking into it and sorry it turned out to be a bit of a wild goose chase.

No problem, thanks for reporting initially. It's good to be aware of these issues in case there is something that can be done by the maintainers.
