When moving the camera / zooming in - out, a “ghost” polyline flickers across the screen.
The issue does not reproduce all the time - some playing with the map (zooming in and out and moving is needed).
The issue is reproduced in the following sandcastle example.
Any help would be appreciated.
It took me a moment to find it. I had to zoom out pretty far, and scroll around a bit. But it’s actually not only “flickering” in. There are view configurations where it is rendered constantly. For example:
(For similar zoom levels, the pink one can be rendered as well, sometimes “broken”/interrupted in some way).
There are many open issues that are related to polylines in 2D. The one at PolylineGeometry 2D rendering incorrectly at certain zoom levels · Issue #5726 · CesiumGS/cesium · GitHub sounds “most similar”, but given that this (apparently) was never really investigated or addressed, it’s hard to say whether it’s exactly the same reason.
