Rendering fails - 'Vertex shader failed to compile'

Installed the workshop to see if I can use it for teaching Cesium, but found this error when starting up from both `npm` and `python`:

```
An error occurred while rendering. Rendering has stopped.
RuntimeError: Vertex shader failed to compile. Compile log: ERROR: 0:50: 'w' : vector field selection out of range

I am on Kubuntu 22.04. I tried installing WebGL drivers to fix this, but it didn't (and Cesium works in general for me as well, so it's not something across every Cesium application)
