I've got Koreader running on a 2017 Macbook with a retina display. The window drawn is four times the size of the actual content (see attachment).

Things work fine on an external monitor, including a 4k one.

I've been poking at the source and can't figure out where the window or canvas is created. Could anyone point me at an appropriate place to start looking?

Thanks!
