Hi! I'm probably extra late on this, but I do wanna report something I haven't been able to fix.
The background image option seems to be somewhat bugged (at least from what I can tell), because for some reason the image is overlayed twice, one on the grid itself (which is what I want), but another on the overal map view, causing a very distracting view. Some examples

<(This ones especially noticable because Im fully zomed out, and the background image is too, but
also, theres the same image ontop at normal size)
I only want this to fit with the grid itself, that way I can have the actual map ontop and work from there. If anyone knows how to fix this it'd be greatly appreciated because this is making me batty LOL
