New format on 'follow course'-line

I've had my 6x for 3 weeks. From the beginning my 'follow course'-line was like it always been om my 5x, a purple, thick line with black borders.

Now, it's thinner or maybe just the black borders have been exchanged to white borders.

Does anyone know what I can have changed or can it be a new map definition? I've tried to disable all Garmin maps and only have the osm map and custom maps enabled.

I'm still on v3.00, gps:2.50, ciq:3.1.2, bmx:0.4.8, ant:4.18, sns:2.40

I've updated maps, ant/ble and sns since beginning.
