Hello
In my code i need get the id of the objects previously drawn in the map, i do that handling a MOUSE_MOVE event. It works fine but when the sceneMode is 'SceneMode.SCENE2D' (also columbus view) the handler plus scene.pick() create a blink in the transparent items when the mouse is moved, when you move the map is even worse.
If you remove scene.pick() from the handler everything works fine.
If you use SceneMode.SCENE3D everything works fine.
so my question is: is this a bug or I am missing something?
As example of it i have used the geometry example and add the handler below the ********.
The next code can be pasted on the sandbox. (sorry maybe it's too long and hard to read)
I'm using cesium 1.10
