[Bug]: 4X upscaling broken with LDSR

[chakalakasp]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What happened?

Upscaling a standard SD render 4X with LDSR, the upscaler first renders once to 100%, then appears to run again, this time on the already upscaled photo. So after the first render is done, after a very long pause my 3090 then begins going at it again, this time with an estimated time of over an hour at 40it/s. Other upsamplers work fine.

Steps to reproduce the problem

1. Render any SD image at 512x704
2. Send to extras
3. Select LDSR for upscaling model
4. Drag model 2 slider to 0
5. Run upscale job

What should have happened?

Image should be upscaled 4X by LDSR algorithm
