img2img mask misalignment?

[MosJef0]

Hi all, sorry if this has been covered somewhere else, I searched but did not find any information on this issue:

When I apply a mask to an image in img2img, the masked area(s) in the output images are not located in the same location(s) I drew them. The masks are doing their job (either excluding an area from being reprocessed, or selecting it as the only area to be processed), but they are always misaligned (and possibly smaller?) from where I drew them.

I am using the networking functionality of the webui/gradio interface and drawing the masks on my phone, so maybe that is affecting it?
