Where can I get the one good with 256x256

[Pang-0093]

Hi there!
I want to operate on 256x256 size images. I try to set the --H and --W to 256 and prompt the SDv1.4, but I usually obtain some corrupted images (and when H and W are 512, all is well then).
The model card shows that the SD1.4 is pretrained on 256 and finetuned on 512. So I assume that the diffusion module is finetuned to fit 512 size more.
I want to know is the SD1.4 pretrained on 256 size published? or where can I get the good one with size 256x256?
Can anyone help me out? Thanks a lot!

you could use this model https://ommer-lab.com/files/latent-diffusion/text2img.zip
