This Sandcastle renders a Cylinder.
It looks good on a windows machine, and looks bad on a MacOS machine.

The radius seems to be the main culprit. Increasing the radius improves rendering, but doesn’t fix it.
Any idea why?
Here are some WebGL reports:
Windows machine which renders a cylinder well:

MacOS machine which renders a cylinder poorly:
We’re seen some issues on machines with M1 chips with precision, including Tileset Highlighting Distortion (M1 hardware on iOS 12) · Issue #9907 · CesiumGS/cesium · GitHub and Tracking Entity - Path Jitters on iOS & new M1 Macs · Issue #9417 · CesiumGS/cesium · GitHub. These appear to be linked back to a webkit bug related to precision on M1 chips.
Is the version of both OS and browser up to date? Additionally, I believe there is a fix in the latest version of Chrome Canary.
