# Known Issues for Unreal Engine

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.

# Unreal Editor startup issue

Some firewalls could prevent the Unreal Editor from starting up correctly. A way to fix the issue could be by renaming the CrashReportClientEditor.exe to something else in the Unreal Editor's install path under Engine/Binaries/Win64.

# Hand Tracking

Hand Tracking will not work when opening a map and enabling the extension directly in Begin Play directly. Adding a delay of one second resolves this issue.

# Rendering issues

# Frame tearing

Under fast movement, the rendered image might introduce tearing artifacts.

# 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.
