230 - VTK::IOImportCxx-OBJImport-MixedOrder1 (Failed)
232 - VTK::IOImportCxx-OBJImport-MTLwithoutTextureFile (Failed)
543 - VTK::RenderingVolumeCxx-TestGPURayCastMapperRectilinearGrid (Failed)

1310 - VTK::FiltersGeneralCxx-TestDensifyPolyData (Failed)
1347 - VTK::FiltersGeneralCxx-TestYoungsMaterialInterface (Failed)

Most of are failing seem t be failing on image comparisons with minor differences, such as VTK::FiltersHyperTreeCxx-TestHyperTreeGridBinaryEllipseMaterial.

I am building VTK with the following configuration:

cmake -B build \
                -Wno-dev \
                -DCMAKE_SKIP_INSTALL_RPATH=ON \
                -DCMAKE_INSTALL_LIBDIR=lib \
                -DBUILD_SHARED_LIBS=ON \
                -DCMAKE_INSTALL_PREFIX=/usr \
                -DBUILD_DOCUMENTATION=OFF \
                -DVTK_USE_FFMPEG_ENCODER=ON \
                -DModule_vtkIOPDAL=ON \

                -DVTK_PYTHON_VERSION="3" \
                -DVTK_CUSTOM_LIBRARY_SUFFIX="" \
                -DVTK_INSTALL_INCLUDE_DIR=include/vtk \
                -DCMAKE_BUILD_TYPE=None \
                -DVTK_MODULE_USE_EXTERNAL_VTK_hdf5=ON \
                -DVTK_MODULE_USE_EXTERNAL_VTK_netcdf=ON \
                -DVTK_BUILD_TESTING=ON

I think the most likely issue here is perhaps some version conflict with the external dependencies, but I don’t have a ton of experience working with VTK. Here is the test log produced with ctest -a --rerun-failed --output-on-failure.

This looks to be a known issue with some graphics drivers. I’ve seen this in our CI where vertical lines end up not rendering correctly. I haven’t had any luck tracking it down other than it was Linux-specific.

The issue is here, but the CDash links have expired since.

That would make sense. I’m also running this in a CI context, using non-accelerated rendering with mesa-dri-gallium and running ctest with xvfb-run so that X is available.

What we do is just exclude tests that have these problems in our CI. I don’t think there’s been anyone that’s had time to investigate where the problem(s) actually lie (VTK, driver, or Mesa).
