Known Issues for AR

There are currently a couple of known issues that may affect the development workflow. These are known issues and will be tackled in future releases of the Unreal Engine plugin or the Snapdragon Spaces Services runtime.

If an issue is not present, check the overall SDK Known Issues.

Reset Position

Resetting the map position on map load is currently not working as expected.

Rendering Issues

Widgets Performance Issue

When the app is deployed with the default Development configuration selected, the framerate and performance decreases heavily when looking at world space UI (widgets) on the Viewer. Unfortunately, the root cause of this issue is unknown. When encountering issues with widgets, the Shipping configuration should be selected instead.

Crash When Using Vulkan with Mipmapping in Unreal Engine 4.27

Building Snapdragon Spaces applications that use mipmapping with Vulkan will result in a crash. Disable generating mipmaps by setting the Mip Gen Settings dropdown to NoMipmaps in the texture settings under Level of Detail. This bug does not affect Unreal Engine 5.3.

Stereo Layer

Rapidly changing visibility of a stereo layer component will result in a crash for shipping builds on Vulkan.
