Hi, I currently have an application where we are streaming time-dynamic czml using the availability and interval properties. We receive the data which consists of billboards, labels and poly lines with material styling from a web socket.
I’m noticing in both Chrome and FireFox, much more noticble in FireFox that the polylines tend to flicker and occasionally lose styling. It seems to happen randomly.
All seems to be working well from a movement perspective and the flickering does not occur with the billboards.
We render the czml via a czml data source using the ‘process’ function every second.
The czml document has a clock interval defined with a start as the current time through a end as current time + 20 seconds.
Each availability and interval for the czml child packets are defined with a start as the current time and an end as the current time + 2 seconds.
I’m curious if there are limitations to the rendering speed for polylines? Or perhaps I’m using the availability/intervals incorrectly for polylines?
We are running Cesium 1.48.0, FireFox 60 Quantum 64-bit and Chrome 64-bit.
