I don't know what the cause or full solution is, I'm getting this as well, but you can reduce the effect by going into settings and reducing the tile size on Swin. I dropped it down to 32, and it's just a sliver of a bar. Easily cropped out.

I have the same issue, 2 black tiles in the exact same position as you have mentioned. I couldn't find any solution for this issue. Any help would be greatly appreciated.

fixed for me on Mac MBA M1 by decreasing tile size settings > upscaling > SwinIR tile size to 128 ish
