Warning when volume rendering disk example
On MacOS 10.14.6, ParaView nightly binary 5.8.0-RC1-87-g944a1bb4
Volume rendering something, for example disk_out_ref.ex2, causes this warning to pop up:
Warning: In /Users/kitware/dashboards/buildbot-slave/a64f5607/source-paraview/VTK/Rendering/VolumeOpenGL2/vtkOpenGLProjectedTetrahedraMapper.cxx, line 290 vtkOpenGLProjectedTetrahedraMapper (0x7fcc6c7cccf0): Disabling floating point framebuffer: Unsupported hardware. Volume rendering will continue, thoughartifacts may be present.
Is something unsupported with my machine? Can this be ignored? Volume rendering seems to work fine. I haven't seen this warning before.
