Description

same problem as above. But with the hires Fix
On the hires. fix, even with very low resolutions (1152x896 x1,3), with a LoRA, after 50% (when enlarging), generation becomes extremely slow. With the same seed and settings, if I don't stop generation I get 16s/it instead of ~3.
Once again, stopping/restarting the generation sometimes makes things run smoothly.

Research direction

Start by reading the related issue #1634 and reproduce the Hires. fix case with the reported seed, settings, LoRA, and 1152x896 resolution. Compare generation speed before and after the 50% enlargement step; done means the run no longer slows from about 3 to 16 seconds per iteration.
