The Recoil map file format includes a 1024x1024 minimap image. The map is stretched to that square, regardless of original aspect ratio, and in game Recoil restores the original aspect ratio.
#815 points out that when selecting a map, the square minimap is shown as-is, without aspect ratio compensation. However, the opposite bug can be seen in its second screenshot, with the map shown in lobby:

The map is 20x10 Recoil units, but is shown with a 4:1 aspect ratio instead of the expected 2:1. Similar double-compensation occurs for other non-square maps.
