When creating a offline region, we've previously only requested the sprite image for the specified resolution. This lead to offline packs not being usable on devices that have a different pixel ratio. We're now requesting both 1x and 2x sprites. Some devices use even higher or fractional pixel ratios. However, we only ever use 1x and 2x sprite images in our requests.

To clarify, this doesn't change the sprites we are downloading when viewing a map in regular operation. It only requests both when creating an offline pack. This is necessary when creating an offline pack on one device, and transferring it to another device with a different pixel ratio. |
