I’m noticing that my tile borders are visible in the product mockup when the tile includes zazzle shapes. Specifically, rectangles created within the design tool using the “Elements” tab.
Steps to reproduce: On a blank product, create a black rectangle with border of 0 thickness. Then tile it. On the product mockup, the background color shows through at the borders of the tiles.
I believe that this is a bug, because (1) solid rectangle should tile perfectly. And (2), if I create a solid black rectangular jpeg image and tile it, then it does tile perfectly with no visible edges.
It appears that there is some anti-aliasing around the edges when the element is rasterized for the product mockup, and this is leaving a transparent border through which the background is showing.
