Description
Environment
- Xcode version: 14.3
- iOS version: 16.4
- Devices affected: All
- Maps SDK Version: 10.10.1
Observed behavior and steps to reproduce
After adding a custom Map Style created using the Mapbox Studio MapStyle maker, maps and layers on the map are low-resolution. It is hard to demonstrate, but see this screenshot (zoomed in):
You can see a clear, high res line in dark gray, which is a ui element in my app. Below that is my custom map including a LineLayer with a width of 3. As can be clearly seen, the line is very low resolution. The Map is too, but it is harder to see in this light map style.
Expected behavior
The map should be just as sharp as the standard map design. All Layers should also be sharp.

Research direction
Start by reproducing the issue with Xcode 14.3, iOS 16.4, Maps SDK 10.10.1, and a custom Mapbox Studio map style, comparing it with the standard map design. Check the rendered map and LineLayer at the affected zoom level; done means the custom map and layers are as sharp as the standard map.
