Description
Xcode version: 14.2
iOS version: 16.6
Devices affected: All
Maps SDK Version: 10.16.3~11.0.0
When using the raster method to load tiles, or when loading a normal image, during navigation in forward motion, there is a noticeable back-and-forth jitter in the tiles or images. I have tried loading different tiles and images with raster, and also switched between different versions of the SDK, but the jittering still exists. How can I resolve this issue?
In the video:
From 0 to 10 seconds, there is severe shaking when turning.
From 37 to 50 seconds, there is a regular back-and-forth shaking from left to right.

Research direction
Start by reproducing the reported forward-navigation jitter with raster tiles or images on iOS 16.6 using Maps SDK versions 10.16.3 through 11.0.0, comparing the behavior with the attached video. Done means the tiles or images remain stable while turning and moving forward, or the cause and required workaround are documented.
