Browser Memory Creep...

1. A concise explanation of the problem you’re experiencing.

I have a czml document that is streamed to the browser (Chrome v71) every 100 milliseconds. The czml document contains a billboard with icon, label, polyline and a path. Each new czml document performs a process essentially just updating the position on the bound datasource as time increments.

Chrome’s memory seems to continually creep up over time until it eventually crashes. Is there some sort of known memory leak in Cesium or with Chrome?

4. The Cesium version you’re using, your operating system and browser.

  • Cesium v1.57

  • Chrome v71

This certainly sounds like something we’d want to look into. Are you able to replicate this issue with a CZML you can share and a Sandcastle ( example?

I’m not aware of a known issue for this, but that’ll help us isolate and fix it.
