**Short description of error**
There are some weird black outlines popping out during anim playback or scrubbing.

**Exact steps for others to reproduce the error**
* open the file and playback the animation, if you can't see them then it's best to slowly scrub the anim cursor back and forth....the black outlines will appear but the moment you stop they'll disappear, so you can screen capture the moment to check their existence ***P**.* open the file
* If it is not already set, * Best to set viewport shading to material preview, (that's where you can easily spot them)
* playback the animation or quickly move the object
