Breakout circle appears through graphics

[theranch]

When using the navigation mixin to zoom in, we are seeing a circle appear that expands and contracts if you use the mouse to move the globe view up or down.
This "breakout circle" appears like it is punching through the layers displayed on the screen.
I've drawn a red rectangle around the breakout circle in the attached image.
This breakout circle disappears when a user uses the mouse scroll wheel to zoom in/out.

This is the only version number that I could pull from the minified code...
Version: a.version = "3.4.0";

What browser are you using? Browser version?

Please check that you have the latest graphics drivers.

Version of Cesium?

Thanks,

Also, the breakout circle is centered on the screen. This circle only appears after clicking the "+" button twice when zooming in.
