TL;dr:
SBXL a.k.a Codename PAI.
An attempt to trying to fix NoobAI XL v1.0. Kinda failed and successful in some ways.
Some generations are better than NoobAI, but in a rare condition, some are WAY worst. 100% happening only on white background. No issue on non-simple background.
Sweet spot is around 20-29 steps, and CFG 4.
Probably will do another attempt, but no funds for now.
