Can't hide point entities

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

If i create an entity with point graphics and change its “show” property to false it doesn’t hide, instead, it positions itself in the center of the screen while still being visible.

this issue only occurs when I’m in a Ubuntu environment

2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

Cesium version: 1.60

Operating system: Ubuntu 18.04.2 LTS

Browser: Google Chrome Version 76.0.3809.87 (Official Build) (64-bit)
