If I remember correctly, the overlay file does not guarantee, which line is
displayed on top. So if not one of the lines is transparent, the display of such
a structure will vary.

If you are using a transparent code for the roundabout, you could also add a
second non-routable line for the display, without using the overlays file, e.g.:

Lines file:
junction=roundabout & highway=secondary [0x0c road_class=2 road_speed=3 level 4
continue]
junction=roundabout & highway=secondary [0x04 level 4]
