I agree the 0-height could be useful for some applications, that's why I didn't create the PR initially and only made an issue. However, in the fiddle I provided there...

Has there been any progress on this issue? I'm hitting this problem at the moment. Is there a good workaround?

I'm having the exact same problem with `mayavi`, I believe it is a problem with `vtk`/`Xvfb`. Is there any alternative to `Xvfb` for headless rendering?

Thanks @akaszynski. I started again with a minimal conda environment (python=3.9, no `mayavi`). I installed `vtk` with `pip install https://github.com/pyvista/pyvista-wheels/raw/main/vtk-osmesa-9.1.0-cp39-cp39-linux_x86_64.whl` then installed `pyvista` with `pip install pyvista`. The OP example...

Thanks! It was linking issues and user errors. It is now compiling nicely and working with ipopt. Although gpus aren't being detected or used in the ipopt examples. Will try...
