The [isosurface example from the Makie docs](https://makie.juliaplots.org/stable/plotting_functions/volume.html#volume) doesn’t render correctly (see image below). Has anyone come across this problem?

Potentially relevant glxinfo:

```julia

Pfew… My only explanation for this is an AMD driver bug, since this has been working anywhere else for years (including the (pretty bad) Mesa software implementation of OpenGL on the CI).

Not sure how to debug this, without access to that GPU… Maybe you can try to update the drivers?

I’d also make sure to be on Julia 1.6.1 and `]add Makie@0.14 GLMakie@0.4.2`, but I don’t think that can be related, since this hasn’t changed in years…

Ok, I tried this on the Ubuntu live CD with the same Julia and Makie versions and it worked fine… I guess it probably is a driver issue then. Thanks @sdanisch.
