What happened?

When I try to inpaint an image in any way instead of it properly inpainting it just oversaturates the colors of the area I've drawn over

Steps to reproduce the problem

1. Go to img 2 img inpainting
2. highlight the area you want to inpaint
3. click generate

What should have happened?

Inpainting should have slightly altered the image

Additional information

I'm using a 5700xt
I noticed that if I change the argument line in the batch file to include the argument "--no-half" inpainting does seem to work but it only functions the argument "lowvram" if I use "medvram" it will say my gpu ran out of vram and not generate any images, a way around that was to keep using lowvram but that greatly slows down the generation process and it causes the runtime error where you run out of Vram anytime I tries to resize an image or use highres fix.

I'm very new to SD and this has been making it very difficult to generate anything decent looking, any help would be greatly appreciated.

forgot to add an image in the original post but this is what it looks like after inpainting if that help

Hey, as you already found out, using the Webui on DirectML needs --no-half to get inpainting to work.
But this also makes image generation slower and even more vram heavy.
There is no workaround for that.

The best solution is to install the webui with Zluda instead of DirectML.
This improves the image generation speed by a lot and reduces the vram needed for higher resolutions and tools like hires fix too.

You find the Automatic1111 with Zluda Guide here:
https://github.com/CS1o/Stable-Diffusion-Info/wiki/Webui-Installation-Guides

Currently its Important that your AMD driver version is not 25.5.1 because that breaks Zluda.
But that also should be fixed in the coming days.
