Multidiffusion sampling 48%

[IDXoX]

When I use "Tiled Diffusion & VAE" to enlarge the picture, the progress bar of "webui" is 100% finished and the picture is produced, but in the background launcher, the progress bar of "Multidiffusion sampling" is always slower than that of "Total progress". As a result, "Multidiffusion sampling" has not completed its work after drawing, how to solve this problem?

In addition, this problem is more obvious when using "Tiled Diffusion-RegionPormptControl", "Total progress" is 100% complete,and the "webui" picture is displayed, However, the "Multidiffusion sampling" progress bar only went up to 48%, resulting in very poor object fusion.
