Failing tests on Windows with GH artifact wheels

[jdegenstein]

Using an appropriate wheel from https://github.com/CadQuery/ocp-build-system/actions/runs/8367440736

I created a conda environment and discovered that 2 tests from CadQuery/cadquery are failing. Here is my setup process:

conda create -n env1 python=3.11
conda activate env1
pip install cadquery_ocp-7.7.2-cp311-cp311-win_amd64.whl # this also installs vtk=9.3.0 on my system
pip install cadquery
pip install ipython pytest
git clone https://github.com/CadQuery/cadquery.git
cd cadquery
python -m pytest

fails 2 tests and returns:

@jdegenstein Is this on Windows 11?

[jdegenstein]

This is on Windows 10

@jdegenstein I can reproduce on Debian 12 with the wheel with mangling disabled, and Linux gives some extra info.

@jdegenstein can you try VTK version 9.2.6 instead of 9.3 to see if that fixes the issue on Windows 10?
