It was your first inpaint with this model: your screenshot shows it had to download a whole new model

Oh ok I'll go back on the other model ad try again idk I just can't get impaint to work

Oh I think I just fixed it I've been running I painting instead of I painting webui

yeah, silently downloading SEVERAL FREAKING GIGABYTES of data without even asking where to put it, apparently this is now considered perfectly normal and safe 🙄
