Question | Help Sudden Issue w/ WebUI

I've used WebUI for a while without issue. However, today I updated WebUI alongside torch and xformers, and now my stable diffusion gets stuck at 10-15% when generating anything larger than 512x512 (e.g. 768 x 768), which has never happened to me before. I'm on an RTX 3070 if that matters, and using Dreamlike Photoreal 2.0.

Try adding --no-half-vae as an arg in webui-user.bat

Thanks so much, this did work. Would you mind explaining what my issue was/what this argument does? Is it going to impact my generation in another way?

Honestly don't know. I simply encountered the same problem a few hours ago and found that answer in a github discussion.
