On the attached slide layer, the base layer background is showing through on the left side and I'm wondering why and apart from making a filled square to cover it on the slide, what can be done to have the background on the layer fill the entire space so the base layer background does not show through. The attached pic is of the slide published. It also shows through in preview mode.
Any help appreciated!
Not sure how you size and place your slide layers, but one thing you could do so base layer won't show through:
Slide layer (right click) -> Properties -> Visibility -> Hide objects on the base layer.
It might lead to some white space popping up on the left in the preview and publish. I'd also purpose you to enlarge the background image of the slide layer, so that its edges are slightly over the canvas. Doing so, no matter it shrinks or not, it would cover the entire screen.
Based on the image, it looks like you have a filled rectangle as the background object on the layer (or possibly on the Feedback Master Layout applied to that layer). And that rectangle isn't covering the entire slide. For example, the rectangle might be somewhat narrower than the slide and aligned on the right. Or it might be the same width as the slide, but moved slightly to the right. If either of those is the case, that's why a small strip of the base is showing through on the left. The solution is to adjust the size and/or placement of the rectangle.
If that's not the case, well, troubleshooting is just guessing without seeing the .story file. If you upload it, someone might be able to solve the issue. Here are the best practices for doing that:
