Body tracking within a group - strange joint positions that don't appear to update for some people

Hi, today I was performing a group test with the Zed 2i- tracking people via body tracking (BODY_TRACKING_MODEL::HUMAN_BODY_FAST + BODY_FORMAT::BODY_18). I screen recorded for about 2 minutes- and noticed the joint positions of 2 people in the group were distorted and appeared frozen but still continued tracking the users main position as they walked around.

Have attached 2 screenshots- showing the issue. Tracked user ID 173 (left of first image) and ID 124 (right of 2nd image).

Was wondering if this is common issue / bug / or any advice on how I could fix?

Hi @trent ,

First, sorry but to my knowledge it’s not a common issue.

What version of the SDK and what depth mode was being used?
Can you share the result of ZED Diagnostic (Windows: C:\Program Files (x86)\ZED SDK\tools\ZED Diagnostic.exe / Linux: /usr/local/zed/tools/ZED_Diagnostic) and a SVO reproducing the issue to It will help a lot in investigating this quickly.
