Layers in composite map are long rectangles instead of squares in max 2018 corona 1.7. This problem does not appear in max 2016 corona 1.7.
So right now i can’t see which map is which.

Is this happening only when Corona is used?

This is a general bug in 2018. There are more issues related to the Composite Map (UI redraw problems, ordering of layers not permanent), but none of them is related to Corona.
