Description

In Input 2.x, using a ArcGIS REST raster layer is very slow - both to load and to render - at least on Android. On desktop build it seems fine. Not tested on iOS.

URL that can be used for testing:

https://gis.blm.gov/nmarcgis/rest/services/Base/BLM_NM_Surface_Management_Agency/MapServer

On Android, it takes a minute to load the project with such a raster, and also rendering can take long (>10 seconds).

Research direction

Use the provided ArcGIS REST URL to reproduce the slow project load and raster rendering on Android, then compare with the desktop behavior described in the issue. Trace the ArcGIS REST raster loading and rendering path; done means resolving the reported Android delays, though the issue does not name files, tests, or a precise performance target.
