Is latent upscaling broken for this model?

How do you do an ai latent upscale without causing massive suffering to the quality? Workflow would be helpful

Yea upscaling over a certain resolution makes the model break down in an odd way. I wonder why since at low cfg/denoise you can even push SD1.5 beyond these resolutions.

dpmpp_2s_ancestral_00028_
Out:
Illu_00015_

for now tiled upscale seems to be the only real choice (just have to deal with artifacts)

I can't do that either. My latent upscale workflow is fine on non overfit models, but not this one.
