stable-diffusion-webui Maybe hint for black image bug

When I try dump every step result of image, I found some of them can be black, but the steps before and after can be ok, It seems this bug is in dump image from latent, maybe related to multi-thread.

Do you have "--no-half-vae" after "set COMMANDLINE_ARGS=" in the webui-user.bat? If not, that should fix it. it's a known problem unfortunately.

No

so it is a vae related bug?

yeah, something with the vae file has been messing stuff up for a couple of days now, I personally had it working fine for a while, but after some updates, can't remember when exactly, I had to use this command as well.

Can confirm this issue is present when any vae is used, but why is that?

And --no-half-vae fixes the issue for my 3080, what's the effect of that commandline even

That fixes the bug, but seems to decrease it/s?
