As I posted as a comment on the Remote 1.2.6 launch, on our Mac computers, main view or a custom stage view that gets core/live-image, OpenLP returns an image from the main screen, not the actual live view. At church the display is set to 1920x1080, which is what OpenLP sees and uses. At home my second display is an iPad at 1116x756. But on either Mac, the main view or custom stage returns a 1920x1080 image taken from the top left of the main display, which is a lot bigger than that.
I'd send an image, but the forum isn't letting me upload anything.
This isn't a deal breaker, but our custom view is designed for someone with low vision. For text, it uses a jquery library to expand the text to fill the screen and used to show an image if that was projected. Our user can get by without seeing the images, but it's not ideal.
I've tried the Advanced setting "Prefer window capture...", but then OpenLP crashes any time we try to get an image. That was an old Mac problem we left behind some time ago.
