I was creating and working with vectors in Adobe Fireworks (!!) and some Inkscape (free) and I found no trace of this problem before I switched to Affinity Designer. However I found more issues I never faced before in any vector software.
 
1) the stroke inside setting within a filled path leaves visible background fill color visible as a thin line on the outer edge of the stroke (or path, or object).

2) Another problem is Affinity D only because of nested/masking paths feature is possible within AD only. The thin white line (this one is always white no matter of the BG fill color or if the stroke even exists) is visible when child (nested) path is placed over the edge of the parent path so the child path is partially masked behind the edge of the parent path. The white edge is visible where child and parent paths are "touching" or crossing over each other. So this is a serious rendering problem - obviously not edge near edge related as this is path crossing / overlapping edge -  that affects the work and on large projects there are no easy or quick fixes for this as it becomes a designers nightmare.

Hello. I watched affinity designer more than a year. As soon as the beta for windows I downloaded it immediately. Once the program came from the beta - I bought it immediately. Soft good, very good. So good that I almost immediately replaced by CorelDrow and Photoshop.
 
I immediately tried to use Affinity Designer for Web Design. And experimental success! But two things I was very disappointed: 1. I made a design, and then what? Adobe brackets - works well, but the PSD files in affinity is not very good. Because text. The text is translated in a raster. Because of this, it is impossible to take css for text. Avocode - this is again psd. Again the same problem. Zeplin. I was not able to import the template file, because you need to download the plugin for Photoshop. And I do not want to use Photoshop. I now appeal to Affinity Designer developers. Look at this: https://zeplin.uservoice.com/forums/255350-got-any-suggestions/suggestions/8480671-support-for-affinity-designer Members Zeplin want it. Members Affinity disigner want the same. Perhaps you could work together for this !? I finished the layout for the site, but it was hard. Without a suitable tool for the layout of the site, work hard. Please pay attention to it. I'm not alone in his desire to https://forum.affinity.serif.com/index.php?/topic/16975-zeplinio-integrationcooperation/ 2. Typografy. Affinity designer allows you to assign styles to text. As <h1>, <h2>, etc. or as a <p> <ul / li>. But the styles of text to work inconvenient. I would like to work with typography as well as going to work with symbols. If there was such a possibility - this would be ideal. Thank you for your work. You've done a terrific product. I hope that in time he will become only better. P. S. Sorry for the broken English. I hope it will also better with time))

I would like to confirm that duplicating the same object on top does seem to fix this issue temporarily, which confirms it being an anti-aliasing issue.
Adding a thin inside stroke of 0.1 or 0.2 pixels of the same color as the shape seems to be a workaround as well.
 
Hopefully a real solution can be found, but I'm sure it is no easy fix.
