Hi all,

I’m currently having the following error while running VTK8.2 on the new Mac Mini 2018:

> ERROR: /VTK-8.2.0/Rendering/OpenGL2/vtkOpenGLImageSliceMapper.cxx, line 485  
> vtkOpenGLImageSliceMapper: failed after RenderPolygon 1 OpenGL errors detected  
> 0: (1286) Invalid framebuffer operation

The app still run but it keep printing the same error which slow down the app. Not sure if it is because of the new Intel UHD graphic card.
