The bug has been reproduced following these steps:

1. Download a Heightmap for your region in the app.
2. Navigate to Menu > Configure Map > Terrain and enable the terrain layer.
3. Return to the map and locate a hilly area where the terrain shading is most prominent.
4. Observe that the topographic relief layer displays with 100% opacity by default, obscuring other map details.
5. To address this, go back to Menu > Configure Map > Terrain and tap Terrain - Appearance > Visibility.
6. Reduce the visibility to 50% and compare the results. You'll notice that at 50% visibility, the map details become much clearer while the terrain remains visible.
