Is there any other layer loaded? It looks like there is at least another overlay on top of the volume layer?

That’s indeed strange. I wonder if it is a graphics card issue. Does the blue tone appear all the time? on any volume?

So it happens with freeview all the time? Freeview uses openGL as backend for rendering, which I believe is not the case for fslview. Would it be possible for you to update your graphics card driver?

This sounds very likely a video card/driver issue. Would it be possible for you any other program that uses OpenGL/vtk, such as 3D slicer, Paraview? How does glxgears command show?
