I just noticed when doing an exterior rendering that if I have it set to Medium 300 DPI, after the rendering gets to 100%, a large black rectangle appears in the left upper quadrant of the image, from the left edge extending inward. It looks like the rendering didn't fully complete, even though the black rectangle wasn't there before it got to 100%. When I switched to Medium 150 DPI, I don't get the rectangle, but I do get a black line across the middle of the left half of the image, that more or less appears to be around where the top part of the bottom black part of the image shows during the rendering process, before the rendering completes. But again, the black line doesn't appear until after it reaches 100%. Anyone else seeing this?
