It seems like there is a difference between the width in the desktop preview size, than its actual pixel width.

i recorded a loom to explain it:

the artboard screen width size is 1920px
the screenshot of the desktop preview size is 3492px

maybe xd should think of alerting the user that in those cases the preview isn’t the actual size, so it will be less misleading?
