Hi,
[Apologies - no idea of how to make a reproducible example of this...]
On a couple of occasions when saving ggplot2 objects (using ggsave()), images have appeared different when viewed on different machines.
For example:
Screenshot, when viewed on my Mac, with macOS Mojave 10.14.6
Screenshot of same image, when viewed on my collaborator's Windows PC, with Windows 10
(You will notice that the geom_ribbon()s have disappeared.)
This has happened previously, also with geom_ribbons().
Very grateful for any hints as to what might be going wrong, or how to overcome.
Thanks
