Errant path graphics on Entities

I am building a visualization with ~100 entities that I add to the Viewer via Viewer.entities.add. These are entities that have long flight paths, and I display the flight path using PathGraphics. When I view the globe, I see errant lines connecting various flight paths. These flicker on and off and change locations when I adjust the time via the timeline slider. The errant lines seem to be connecting the flight paths of disparate entities, but not in a consistent manner. The lines jump around.

At first I thought it must be an issue with the data I’m feeding the entity, but I am confident that is not the issue. The problem goes away when I simply remove ~half of the entities from the Viewer. It doesn’t matter which half I remove. It seems to be tied to the quantity of entities/data that is being used.

Is this a known issue? Is there a way I need to configure the PathGraphics to perform better?

Thank you!
