Hey Cesium Folks!
We've been seeing an issue lately related to memory usage when using Cesium, and for a little while we thought it was something on our app's end. But we recently discovered we can reproduce this on cesiumjs.org!
By simply tilting/panning the map you can see cesium's memory usage grow and grow ad infinitum. Taking a moment to let the globe sit, you'll notice that some of this memory gets released, but still doesn't look so good.
The best way I've been able to reproduce this:
* Open up your task manager to the Processes tab
* Navigate to http://cesiumjs.org in your preffered browser
* Click Tap to Interact
* Keeping an eye on your task manager, start middle dragging to tilt/orient the camera. You should be able to see your memory usage grow quite a bit over time
I'm wondering, is this a known issue? And if so, do we know why this is happening or have a recommended fix?
