What are you using to take a snip? I used the tool that comes up when I hit windows-shift-S and it worked fine.
Edit: Just to be clear, click on the image you want to open, so it becomes one of those gallery popup things, then right click on the image, select the picture-in-picture, and windows-shift-s to open the snipping tool on the PIP popup. I can confirm it still works on my side, no black images.
