Contrast / saturation adjustments causes render issues on Linux since Cesium 1.52 #7382
Since Cesium 1.52 tweaking the contrast adjustment (any value != 1) will cause rendering issues on Linux:
Parts appear black, similar result when saturation is adjusted to a higher value. The previous Cesium version with adjusted contrast / saturation worked fine on my machine.

Thanks for writing up an issue @ulrichson.
This has actually been a problem on the Windows side for a long time. I'm under the impression that it was an Nvidia driver bug. On my Linux machine (Ubuntu 18.04.1 LTS) the issue only appears when running under my GTX 1050 and does not happen when using the Intel GPU. It's definitely possible that it's an issue in an nvidia-only share path in our code. (Happens on my Windows 650ti every time).
Maybe someone can finally track it down.
