The design looks correct in preview mode, but when I export a shared link - it breaks some elements of the design. A dark striped background turns light and looks like it has a pixelated pattern (This is not an image, it is just a standard solid rectangle with a dark grey fill). And white boxes become transparent - they do use drop shadows. I have attached an image of what it should look like vs. how it looks in the shared link.
It's a mobile wireframe that doesn't use any images and is around 400 px wide.
Thank you for reaching out and sorry to hear you are having trouble. Would you mind sharing the link with us here so that we can check at our end? Is it happening with every file or with this specific file? Could you please share the OS and XD version of your machine? Is it showing the same result on different browsers as well?
