# Gradle build issue
In some instances, adding a custom controller archive might lead to Gradle caching errors. In that case, removing the temporary Gradle project folder generated in the project folder under
Temp > gradleOut might resolve the issue.
# Hand Tracking issues
- Head movement may induce hand movement.
# UX limitations
- Releasing object can only be performed with the Open Hand gesture.
- In some conditions, occlusion between hands may result in hand inversion between left and right.
- If the hand avatar is displayed, some jitter may be perceived on the finger tips. Displaying an avatar in an AR context is not recommended in general.
