Problem with capture stage to Picture

[Eva]

Hi there, greatest helpers:)

I hope this is the right place to post.Today I am trying to simply capture some images form a project that I am working on. It is shaped by photos simply to get an image to share of what I am doing, and I wanted a better quality than taking a screenshot. But when I capture an image with Image capture, the image that apears is different from what I have created. here are the 2 different images.
Is that a bug? Or simply me who doesn't know how to work this out: ?
All the best,
Eva

 Could you send a picture of your patch to see where it isPerhaps coming from?
