@peternlewis I've got a strange issue going on. Maybe I'm just not understanding something. I'm pretty sure this was happening in version 9, but I'm finally addressing it now (for reasons which are irrelevant).
When I use the menu item "Copy as Image" on my Retina display, I thought the image was supposed to be scaled down automatically. On my computer, it isn't. Example:
So before I post images images from "Copy as Image", I always have to resize them. (Well, technically I don't have to resize them, but I know it's the preferred thing to do.)
I checked the DPI using "Get Image DPI of System Clipboard", and it's 72.
So that's odd, but this is odder: I dragged KM onto my external monitor, which is not Retina, and did another "Copy as Image". The image is the correct size, but its DPI is 144.
I would have thought it would be the other way around - 72 from my external monitor, and 144 from the Retina. But maybe I don't understand DPI. Regardless, the problem still remains - having to scale down the image before posting it here.
What the heck?
